Data for the Effect of different supplementary cementitious materials on compressive strength of concrete

In this rapid urbanization age, cement concrete is one of the most popular and demanding building material. Concrete contains about 12-15 % cement as one of the components. Globally, the annual cement production causes about 7% carbon dioxide contribution in world wise. CO2 emission. which makes the concrete production industry as a source of global warming. The objective of this study is to find out a way of mitigation of environmental hazards generated due to its production. Supplementary cementitious materials (SCMs) are those materials which are generated from different industries like fly ash (FA), rice husk ash (RHA), silica fume(SF) and ground granulated blast furnace slag (GGBFS), etc. These materials have the virtue of improving strength of concrete in higher age if used as a replacement of cement in concrete. During experimental investigation, total sixty-six cubes of size 15cmx15cmx15cm were prepared to determine the strength of cubes for different curing time of 14, 28 and 56 days. Ash Fly and RHA separately used for partial cement replacement with the proportions of 15%, 20%, 25%, 30% and also SF with 10%, 15%, 20% then, 14 days and 28 days and 56 days’ compressive strengths were calculated by compressive testing machine.

在当前快速城市化的时代背景下，水泥混凝土已成为最为广泛采用且需求量极大的建筑材料之一。混凝土中约含有12-15%的成分是水泥。全球范围内，年水泥产量导致大约7%的二氧化碳排放，对全球的温室气体排放贡献显著，使得混凝土生产业成为全球变暖的源头之一。本研究的目的是探寻一种减轻由其生产引发的环保危害的途径。补充性水泥基材料（SCM）是指由不同行业产生的材料，如粉煤灰（FA）、稻壳灰（RHA）、硅灰（SF）和矿渣微粉（GGBFS）等。这些材料若用作水泥的替代品，在混凝土中具有提升其后期强度的特性。在实验研究中，制备了总共六十六个15cmx15cmx15cm的立方体，以测定不同养护时间（14天、28天和56天）下立方体的强度。分别使用粉煤灰和稻壳灰以15%、20%、25%、30%的比例进行部分水泥替代，同时使用硅灰以10%、15%、20%的比例进行替代，并通过压缩试验机计算出14天、28天和56天的抗压强度。
