Effects of Aggregate Sizes on the Concrete Strength

Effects of Aggregate Sizes on the Concrete Strength


In the sense that the materials involved in this project were capital intensive more especially cement, so in carrying out the work one must have to be careful in the selection and collection of materials to be used in the casting of the concrete.

The materials used are coarse aggregate (granite) fine aggregate (sand). The coarse aggregates used in this work were collected from Ishiagu while the fine aggregate was collected in front of the carpentry workshop on the campus.

The test conforms to the standard method test, the ratio used was 1:2:4 and the method adopted was batching by weight, from the mix ratio the relative weight for each material to be used for concrete cube cast was 36, these cubes were tested for compressive strength of 7, 14 and 28 days.

The results of tests involved in the work and that of compressive strength tests were calculated and tabulated as shown in the final tabulation of results.

With the above information, I now recommend and therefore conclude.
