The use of recyclable materials in the elaboration of hydraulic concrete is currently booming in order to reduce environmental impacts and improve the mechanical properties of concrete, representing optimal adhesion between aggregates, cement and water. The objective of this work was to evaluate the mechanical behavior of hydraulic concrete with the addition of nylon fibers and microparticles of PET plastic bottles. The mortars or specimens had their physical properties evaluated in fresh state and hardened their resistance to compression and flexural tensile, for these 6 dosages were made: a control mixture and others with designed fibers. For the execution of the tests, an Amsler universal testing machine with a nominal capacity of 30,000 kilograms and a resolution of 10 kg, calibrated for analysis in accordance with ISO 376, was used. It was evidenced that the flexural strength improved by 80% (c), 75% (d), 80% (e) and 95% (f) at 28 days, for compression an 80% increase in strength was evidenced in all samples with respect to the control specimen. It was concluded that the performance of hydraulic concrete with the addition of PET fibers was better than conventional concrete, the properties of the studied specimens improve with respect to the control specimen.

Through this paper, three main approaches were adopted to evaluate the effectiveness of waste paper ash (WPA) for stabilization on clay soil. First, the physical properties of mixing soil were studied. Furthermore, the swelling potential of mixing soil with different percentage was also discussed. Finally, the compressive strength using unconfined compressive strength (UCS) apparatus was evaluated. It was found that after mixing with waste paper ash (WPA), the percentage of soil passing sieving number 200 and plasticity index reduces by increasing of the waste paper ash (WPA) percentage. It might be attributed to the bonding of the chemical content of waste paper ash (WPA) to the soil particles. In addition, the swelling potential slightly reduces by increasing of waste paper ash (WPA) percentage. Furthermore, the compressive strength increases with waste paper ash (WPA) 5% and 10%.

The use of fly ash in concrete can lessen the burden of its dumping in landfills to protect the environment and soil degradation. We investigated the concrete mixtures incorporating various percentages of fly ash and studied the mechanical properties of high strength green (HSG) concrete. 0.32 w/c ratio was used. Six mixtures were investigated with varying percentages of fly ash (0%, 4%, 8%, 12%, 16%, 20%) with HRWR (high range water reducer) ranges (0%, 0.4%, 0.7%, 1.0%, 1.3%, 1.6%). The compressive strength of the mixture with a dosage of fly ash from 4 -12%, showed satisfactory results. The peak value of split tensile strength was 4.9 MPa with 12% fly ash dosage. Flexural strength in control mixture was observed at 3.73 MPa in 28 days and there was a slight increase in the trend of flexural strength. The compressive strength was achieved till 12% volume of fly ash for 14 & 28 days. It was due to more adherence between the fly ash and aggregate. Fly ash is very suitable to be used in concrete to produce high strength green (HSG) concrete. If we use fly ash in concrete, it can help us cleaning the environment from contaminating materials.

The aim of this research is to test the characteristics of concrete by substitute fine aggregate with iron ore tailings and partial glass powder as in the place of cement. Concrete with waste products such as glass powder and iron ore tailings offers technical, economic and environmental advantages. In this experimental investigation, glass powder is replaced with cement by 10%, 20% and 30% and iron ore tailings with fine aggregates by 30% which is the optimum percentage. To study the role of glass powder and iron ore tailings combination in concrete, The properties such compressive strength, flexural strength, tensile strength and also durability parameters likely water absorption investigation for M40 concrete is carried out with different percentages of glass powder by keeping the iron ore tailings percentage constant. At 30% glass powder substitution as cement and sand with IOT increases concrete effectiveness. The concrete with 10% glass powder & 30% iron ore tailings showed a higher strength compared to the conventional mix for 28 days. Concrete mix containing 10% GP and 30% IOT showed higher flexural strength of 5.05 MPa for 28 days. Splitting tensile strength value is also increasing i. e for 10% glass powder and 30% IOT, obtained splitting tensile strength was 4.48 MPa and modulus of elasticity value was has also increased. Water absorption experiment consequences results that water absorption decreases with an increase in GP percentage. The concrete workability tends to decrease when with glass powder content increase. Concrete containing 10% glass powder and 30% IOT showed maximum strength and it is considered as the optimum dosage.

In this paper, we present an experimental study and statistical modeling of High-Performance Concrete subjected to high temperatures. The main objective of this study is to examine the effect of concrete age subjected to high temperature cycles (ranging from 20 °C to 1000 °C) on the physical and the mechanical properties of (HPC). The compressive strength, flexural strength, dynamic modulus and the physical characteristics were evaluated based on the mass loss and ultrasonic pulse velocity. The experiments have been performed at different age 90 and 210days. The analysis of the results shows that increasing temperature decreases the mechanical properties of the concrete especially after 90 days. The factorial design and analysis of variance (ANOVA) were used to establish the influence of experimental parameters on the HPC. Based on several criteria, mathematical models can be used to predict HPC properties under high temperature.

Due to high consumption of concrete constituents namely, natural aggregates and cement, their de-pletion is observed globally. Over the years, many researchers have come up with alternatives to these basic constituents of concrete. Ceramic waste (CW) generated from ceramic industries (indus-tries producing tiles, sanitaryware, ceramic refractories, ceramic insulators, ceramic crockery) have not found any reuse and is deposited as landfills, which further increases land pollution and also give rise to health issues. The CW can be easily grinded as per required size, which have interested many researchers to use it in the production of concrete. Till date CW has been used as partial re-placement to cement, fine aggregates and coarse aggregates. This review paper discusses the poten-tial of CW as replacement to concrete constituents in the production of concrete and its effect on mechanical and durability properties. The literature review is carried in three parts – review on use of CW to replace cement, fine aggregates and coarse aggregate. The study shows different research-es using different sources of CW having varied properties being used as partial replacement. The effect of replacement on concrete strength and durability is reported

The usage of aggregates has caused serious ecological problems leading to the requirement of an alternative material to meet the demand. The alternative construction material for the upcoming graduates thus chosen for replacing cement and aggregates should not only meet the design and strength requirements but also the ecological criteria. The present research work tries to improve the service life of sea sand concrete by using them in combination with epoxy resin. The scope of the work revolves around the extended to earlier assessment of the properties of concrete manufactured using sea sand as replacement for natural river sand upto 50% and 12% epoxy resin as partial substitute for cement.

The seismic waves transferred to the foundation of a building cause significant damage to the structure, producing its deterioration and instability. This paper presents the results of subjecting a structure to the effects of the earthquake and the physical mechanical properties of the soil, comparing a theoretical model of an embedded support with the structural dynamics model of D.D. Barkan - O.A. Savinov. Three hypotheses are evaluated: i) The negative effects on the proposed buildings are indirectly proportional to the increase of the seismic response characteristics detected in the soils; ii) The characteristics of the soil strata are directly proportional to the increase of the seismic response characteristics of the soils; and iii) The D.D. Barkan-O.A. Savinov model presents a lower range of embedded support than the theoretical model, which simulates a foundation. Some of the most relevant conclusions indicate that the structural dynamics model of D.D. Barkan - O.A. Savinov presents a more specific range in the reactions produced before the seismic forces, and the relationship in both cases is alleged to be indirectly proportional to the indicated characteristics.

A methodology for quantifying the variation of the static friction coefficient µ due to different site surface conditions, and for metallic materials with hardness ratios ρ = 0.5 – 2, is proposed. ρ is defined as the ratio between the material hardness and the A36 steel hardness. For each material, 7 coupons were considered in the site conditions “clean”, “bought”, “polished” and “corroded”. Results show if surfaces are kept as “bought”, µ may increase or decrease up to 20%, if surfaces are polished, µ may increases up to 37%, and if surfaces are corroded µ may increases up to 410% when considering corrosion rates of 90 – 670 µm/year. These increments or reductions were calculated respect to the site condition “clean”. Results also show for “clean” surfaces and for ρ ≤ 1.7, µ is dependent on ρ, for ρ > 1.7, µ is approximately constant. A model for quantifying variations of µ for the considered site surface conditions was proposed.

The construction industry is an important part of the economic sector of a country, therefore, it is important to verify the new management systems that are implemented in the main construction industries of the world. This article makes a bibliographic review of the Lean Construction (LC) philosophy, introduced by Professor Lauri Koskela in 1992, based on the model used by the automobile industry in the 1980s, called “Lean production”. The theoretical bases of LC intend to see production in construction as a process of transformation, flow and value generator, consequently, the objective of Lean Construction is to create good production systems that allow optimizing, reducing, or eliminating flows to improve delivery times. Within the framework of creating Lean tools to improve the management of construction projects, the Last Planner System arises to improve the work scheduling process and the Integrated Project Delivery (IPD) model, which by unifying it with LC becomes the Lean Project Delivery System (LPDS) project execution system, which proposes the methodology to develop construction projects under five phases and 12 “Lean” stages, in which the development of tools that contribute to the generation of value. Finally, the 3D Building Information Modeling (BIM) modeling technology, although not part of LC, is an important help tool for the LPDS model, helping to better understand the construction processes of complex designs to save time in their construction. Under this paradigm, the emergence of new tools gives us a better vision of the future of Lean Construction.
