Abstract. In the latest period, the volume of building material has greatly extended, raising social and environmental concerns surrounding waste recycling. Construction and demolition waste is a significant factor in global generated waste. Construction necessarily requires the use of massive quantities of aggregates. When the structure's useful life is up, it will be demolished, and all of the demolished waste will disposed of in landfills. It became increasingly difficult to identify large areas for landfills. Crushed, graded inorganic particles that have been processed from construction materials and demolition debris make up recycled aggregates. Aggregates that have been recycled for use in high-strength structural concrete. In this work, recycled coarse aggregate was employed to replace virgin coarse aggregate. The properties of both fresh and hardened concrete made from 100 % recycled coarse aggregate which has been internally or externally replaced found, and the effects are compared to concrete by applying the virgin coarse aggregate.

Abstract. The Polymer concrete is first established in the year of 1950s and gained popularity in 1970s repair works, building cladding and floors, as precasts components. The Polymer concrete has found applications in particularly specialised sectors due to its qualities such as high compression strength, quick curings, high specific strengths, and chemical resist. The objective of this experiment is to use destructive and non-destructive experiments to analyse the mechanical behaviour of Polymer concrete using various lightweight aggregates. Using destructive and non-destructive testing, this experiment evaluates mechanical characteristics of a lightweight polymeric concrete comprising four different types of polymeric ratios. The most important component is to reduce weight. Pumice, perlite, vermiculite, saw dust, and rice husk were utilized as light weight aggregates. Destructive tests revealed that raising the polymer ratio increased the compressive, impact strengths, and splitting-tensile, and the energy absorption of light weight polymer concrete. The properties such as ductility, impact energy, energy absorption shows decrease in efficiency. Pumice was discovered to have the best outcomes among the various lightweight aggregates. These study's findings are significant in understanding a performance of Lightweight polymer concrete and ensuring its safe deployment in a engineering applications which requires a high performance of strength to weight ratio material.

Abstract. Cement concrete is a composite and widely used construction material. The motive of this analysis is based on examination of the use of steel fiber in high performance concrete to enhance the mechanical properties of concrete. The utilization of steel fiber strengthen the concrete by resisting the tensile cracking, enhance the mechanical properties, durability and the serviceability of structure. But higher the utilization of steel fiber can decrease the workability of concrete. In such case, fly ash is used in a range of 20-30% to enhance the workability. Also, the use of fly ash can reduce the greenhouse gas emissions. Thus it creates a sustainable environment. Tests were conducted by preparing the mixes and were compared with the normal conventional concrete properties.

Abstract. Geopolymer composites made from sustainable ingredients which are used to make ecofriendly concrete in the infrastructure sector. The dramatic increase in infrastructure growth around the world demonstrates the daily demand for cement production. This study provides an overall view of research on the use of materials and the performance of geopolymer matrix based on strength and durability. Unlike cement, the reutilization of industrial by-products reduces greenhouse gas emissions during manufacture. Hence geopolymers can contribute to a better alternative to Portland cement. Natural raw materials, agricultural waste, and industrial waste by products from diverse industries are used as composite filler / binder materials in geopolymer matrix to improve workability , durability and reducing geopolymer concrete manufacturing costs. With the help of various curing procedures, the compressive strength of geopolymer concrete can be increased in a short amount of time. It has also been discovered that adding fibres to geopolymer concrete improves tensile strength, lowering the cost of structural maintenance.

Abstract. The increasing population results in executing the infrastructure and buildings to be constructed also in weak and soft soil. Therefore, the soil must be strengthened to surrender larger settlements, ground subsidence, etc to resist the collapse of building. In such cases, the necessity of ground improvement has been implemented. The ground improvement techniques is majorly performed for reducing settlement in soft soil, improving the soil bearing capacity, slope stabilization and preventing from earthquake liquefaction. This technique is done for stabilizing the properties of soil and attempted to modify the existing ground. Ground improvement can be done by various techniques i.e., vibro-compaction, dynamic-compaction, ground freezing, Vibro-replacement stone columns, Electro kinetic stabilization, grouting, etc. Recent improvement techniques are introducing Geo cell, Geo-textiles and Geo-membranes has been developed in which the soil is reinforced with materials like aluminum, stainless steel, polyester, fibers, polyamides in the form of strips or grids to stabilize the soil. This paper will give some of the recent techniques adopted in site to improve the soil properties.

Abstract. The concept polymer concrete has numerous advantages over the convention concrete similarly in mortar also which uses reactive silica presented in the pozzolanic materials which is activated using alkaline materials. This paper focused on the Geopolymer mortar with fly ash and clay as raw materials and M-Sand for fine aggregate instead of river sand. Different combinations of mixtures were prepared and compared with ordinary cement mortar. The objective of this research is to identify the properties of different combinations of geopolymer mortars with conventional cement mortar, in which the fine aggregate sourced from riverbeds is replaced by Fine aggregate manufactured using Crushing stones and testing it for compressive strength, water absorption, residual alkalinity, and acid resistance. Fly ash- clay based geopolymer shows good acid resistance and shows less reduction in weight and compressive strength than ordinary cement mortar. Permeability of geopolymer mortar is less that of ordinary cement mortar. Alkalinity of geopolymer mortar is 4-20 % higher than that of ordinary cement mortar. Fly ash- clay based geopolymer has excellent compressive strength (75.7% for red clay and 52.6% for fire clay) than the conventional cement concrete and is suitable for structural applications.

Abstract. Light weight Concrete (LWC) is that the building material employed in the development of building utilization the most recent technology to cut back the self-weight of building. Silica fume is added for achieve strength. Silica fume is added in the percentage of 0%, 10%, 15% and 20%. Light weight Concrete prepared by exploitation light weight combinations (pumice stone) or volcanic stone or silicon oxide. Admixture metal powder as associate in nursing air-entraining agent to the conventional combine concrete. Light weight concrete is restricted to sure functions compared to traditional concrete. However, the introduction of light weight concrete offers additional different to the development business, that presently focuses on natural resources. Light weight concrete plays a distinguished role in reducing the density and to extend the thermal insulation. The density of light weight concrete varies from 1440 to 1840kg/m3. By exploitation the sunshine weight concrete it minimizes the earthquake or any environment impact. Generally, light weight concrete has wonderful thermal and sound insulating properties, an honest hearth rating, non-combustible and offers price savings through construction speed and simple handling. Then light weight concrete is great for rooftop deck fixes, support profiles, raised floor chunks, and floor deck overlays. Light weight concrete has a lower temperature move rate than typical weight concrete, bringing about better protection. The principal advantage of lightweight cement is that it is incredibly fast and comparatively easy in construction. Light weight combination particle strength varies with kind and strength. In some cases, compressive strength may be exaggerated by commutation a part of the fine light weight combination with smart quality natural sand.

Abstract. The by-products from metal casting industries, waste foundry sand is generated in huge amount which causes many pollution to the environment like infertility of sand, unsightliness, awful odour, etc., because of improper disposal. Such kind of environmental problems can be reduced when those wastes are used as building material during concrete production. So, a research work was carried out in concrete containing waste foundry sand in the range of 15% to 25% with 5% increase, as a partial replacement for fine aggregate(M-sand) for M-20 grade concrete. The concrete made of foundry sand in the proposed mix design was tested and compared with ordinary concrete for workability, compressive strength, Flexural strength and Tensile strength. The cubes were tested on 14th and 28th day for mix of 1:1.54:2.97 at a water-cement ratio of 0.45 and the results were carried out with comparison.
