Abstract

Due to the increasing environmental pollution caused by scrap tires, a solution is being sought to recycle and use them in a field of civil engineering, i.e., construction. This paper will provide a brief overview of previous researches that give detailed information on the advantages and disadvantages, considering the microstructural and mechanical characteristics of self-compacting concrete, when waste tire rubber as an aggregate is added. With this aim, a database of 144 different mixtures of self-compacting concrete with partial substitute of natural aggregate with recycled tire rubber (self-compacting rubberized concrete, SCRC) provided by various researchers was created. In this study we show that Gaussian process regression (GPR) modelling is an appropriate method for predicting compressive strength of SCC with recycled tire rubber particles and is in accordance with the results displayed by SEM images.

废橡胶自密实混凝土的微观结构和力学特性
由于废轮胎造成的环境污染日益严重,正在寻求一种解决办法,以便在土木工程领域,即建筑领域回收和使用它们。本文将简要概述以往的研究,详细介绍在考虑到废轮胎橡胶作为骨料加入自密实混凝土的微观结构和力学特性的情况下,自密实混凝土的优缺点。为此,创建了一个由不同研究人员提供的144种不同混合自密实混凝土的数据库,这些自密实混凝土用再生轮胎橡胶部分替代天然骨料(自密实橡胶混凝土,SCRC)。本研究表明,高斯过程回归(GPR)模型是一种预测再生轮胎橡胶颗粒SCC抗压强度的合适方法,与SEM图像显示的结果一致。

期刊介绍: The STRUCTURAL ENGINEERING AND MECHANICS, An International Journal, aims at: providing a major publication channel for structural engineering, wider distribution at more affordable subscription rates; faster reviewing and publication for manuscripts submitted; and a broad scope for wider participation. The main subject of the Journal is structural engineering concerned with aspects of mechanics. Areas covered by the Journal include: - Structural Mechanics - Design of Civil, Building and Mechanical Structures - Structural Optimization and Controls - Structural Safety and Reliability - New Structural Materials and Applications - Effects of Wind, Earthquake and Wave Loadings on Structures - Fluid-Structure and Soil-Structure Interactions - AI Application and Expert Systems in Structural Engineering. Submission of papers from practicing engineers is particularly encouraged.
