Sep 16, 2016 . Use this test method to make and cure compression and flexure test specimens of concrete sampled from concrete being used in construction. B. Apparatus. The apparatus consists of the following: 1. Cylindrical Mold: Use a cylindrical mold made of non-absorbent material that is substantial enough to hold.
We are manufacture and supply a quality assured range of Cylindrical Moulds, which is extensively used for testing concrete cylinders for compressive strength tests. Additionally, these moulds are split vertically into two parts. Our clients can avail these moulds in various sizes at leading market prices. Specifications:.
Any air trapped in the concrete will reduce the strength of the cube. Hence, the cubes must be fully compacted. However, care must also be taken not to over compact the concrete as this may cause segregation of the aggregates and cement paste in the mix. This may also reduce the final compressive strength. Filling the.
