Abstract

The utilization of waste materials from the industries has been continuously gaining emphasis in the construction work recently. The present work is to use Processed Granulated Blast Furnace Slag Sand and Fly ash as combined replacement for river sand and ordinary Portland cement respectively. M35 grade of concrete with W/C 0.4 will be adopted with two percentages of cement replacement by Fly Ash i.e, 30% and 40%, along with this the slag sand is varied from 0% to 100% in step of 20%. In first variation, 30% Fly Ash is replaced by cement and slag sand is varied as 0%, 20%, 40%, 60%, 80% and 100%. In second variation, 40% GGBS is replaced with cement and slag sand is varied as 0%, 20%, 40%, 60%, 80%, and 100%. For all mixes compressive strength, split tensile and flexural strength will be determined at different days of curing. The strength of cube specimens, cylinders and beams will be determined and compared with conventional concrete specimens. The beams are tested for flexure, under two point loading condition. Different parameters will be investigated in detail. In this paper literature is reviewed in detail to understand the experimental analysis.

粉煤灰部分替代水泥，细骨料部分替代高炉矿渣砂混凝土强度分析

近年来，工业废料的利用在建筑工作中不断得到重视。本研究是用经处理的矿渣粒化砂和粉煤灰分别作为河砂和普通硅酸盐水泥的复合替代品。采用M35级混凝土，W/C为0.4，粉煤灰替代水泥的比例分别为30%和40%，渣砂的比例从0%到100%，逐步增加到20%。第一次变化为水泥置换30%粉煤灰，矿渣砂分别为0%、20%、40%、60%、80%、100%。在第二种变化中，用水泥代替40%的GGBS，矿渣砂变化为0%、20%、40%、60%、80%和100%。对于所有混合料的抗压强度、劈裂抗拉强度和弯曲强度将在不同的养护天数确定。将测定立方体试件、圆柱体试件和梁试件的强度，并与常规混凝土试件进行对比。梁在两点荷载条件下进行了挠曲试验。我们将详细研究不同的参数。本文对相关文献进行了详细的回顾，以了解实验分析。
