ABSTRACT

This paper present the study of various strength such as compressive strength, split tensile strength and flexural strength during 7 and 28 day. It is construct the specimens size 15cm X 15cm X 15cm for testing purpose which depend upon the size of aggregate. Test results are indicated that strength performance of concrete well as in durability aspect are improved using of Silica fume.

1.      INTRODUCTION

 

Silica fume, durability and Compressive strength etc are studying and analyze. The mix (M1, M2, M3, M4 and M5) are used to analyze and absorb the optimum mix for construction using of some Calcined Kaolin, Sand and Aggregate.

 

2.      COMPRESSIVE STRENGTH FORMULA

 

Compressive Strength = Load / Cross-sectional Area

 

 

 

3.      PROCEDURE

 

The cubical moulds of size 15cm x 15cm x 15cm are used for testing and analyzing. The concrete is poured and mould with tempered properly to remove any voids, after this 24-hour cubical moulds are removed and test specimens are putting in water for curing purpose. All specimens are tested with the help of compression testing machine after 7 days curing and 28 days curing. The load (150 kg/cm² per minute) are applied gradually at till the Specimens fails.

6.      CONCLUSIONS

 

We are construct the specimens size 15cm X 15cm X 15cm which depend upon the size of aggregate. These specimens is poured in the mould and tempered properly during 24 hours. These specimens are tested using of compression testing machine after 7 days curing and after 28 days curing, after this optimum result are finding out using of Mix (M4) which is shown Table 6-11, and Figure 8-13.
