ABSTRACT

The article is presenting the various type of strength like as compressive and tensile strength during the time of 7 and 28 days. The specimen ore making as 15cm X 15cm X 15cm size for the testing purpose which is depending on the aggregate size. The results are show that strength performances of concrete with durability aspect are improved using Silica fume parentage addition.



 

1.     INTRODUCTION

 

We are study about the property of test specimen which are having size of 15cm X 15cm X 15cm. The property of composition is generally used such as compressive strength and tensile strength. We are tested Mix (M1, M2, M3, M4, M5, M6, M7 and M8) to observe the suitable mix for construction propose, which is making with the help of Calcined Kaolin, Sand, Aggregate and composition.

 

2.      COMPRESSIVE STRENGTH FORMULA

 

Compressive Strength = Load / Cross-sectional Area

 

3.     PROCEDURE

 

First of all, we are constructed the cube with size of 15cm X 15cm X 15cm for testing propose and observing using concrete is completely poured and mould with temperature for the propose of removing the voids after one day cubical mould are removed and the specimen are placed in water tank for the propose of curing. All specimens after time of 7 and 28 days curing, we are tested with testing machine. The load id applied on the specimen 200 Kg/ cm2 per minutes gradually upto fails.

6.     CONCLUSIONS

 

We are tested the specimen size of 15cm X 15cm X 15cm to observe the compressive strength (Kg/ cm2) and split tensile strength (Kg/ cm2). The various results are achieved with the help of % of silica fume addition. These specimens are tested using compression testing machine after 7 days curing, after this optimum result are finding out using Mix (M7) which is shown Table 5, and Figure 10. Using of compression testing machine after 28 days curing, after this optimum result are finding out using of Mix (M7) which is shown Table 6 and Figure 11. These specimens are tested using compression testing machine after 7 days curing, after this optimum result are finding out using of Mix (M7) which is shown Table 7, and Figure 12. Using compression testing machine after 28 days curing, after this optimum result are finding out using of Mix (M7) which is shown Table 8, and Figure 13.
