Effect of Fine Aggregate Sources on Compressive Strength of Cement Concrete

Abstract

The cause of failure of structure made from cement concrete is due to use of low-quality ingredient which is used directly without testing its properties and without studying its suitability in production of different grade of concrete mix. The aim of this study is to presents that the effect of fine aggregates from different sources on compressive strength of cement concrete. For this study four fine aggregate sources were taken. Altogether 48 concrete cubes of M20 grade were prepared from different sixteen combinations of these four fine aggregate sources. The different properties were founded by conducting different laboratory tests for fine aggregates from different sources and the compressive strength test of 48 cubes was conducted.The test results showed that properties of fine aggregate sources such as fineness modulus, loose bulk density, specific gravity, water absorption and Materials Finer than 75 μm were founded in the range of (3.17-3.88), (1508.33-1604.17) kg/m3, (2.57-2.66) %, (1.60-1.92) % and (2.74-7.47) respectively. Compressive strength test of all 48 samples were cross the minimum strength provided by M20 grade and it is ranges from 20.64 N/ mm2 to 32.47 N/ mm2. Different value of mean compressive strength was obtained for all sixteen combinations of aggregates form each other. The fine aggregate from Chisang source achieved more value of average compressive strength when mix with other four different coarse aggregate sample than other three sources. Significance difference in mean compressive strength of concrete made from different fine aggregates source was concluded by the Two-way ANOVA test results. This research work concluded that all four fine aggregate sources used in this study and concrete made from these sources can be used for residential building construction propose and other construction work which required strength provided by M20 grade of nominal mix concrete.
