### Effect of Aggregate Properties on the Crushing Strength

Effect of Aggregate Properties on the Crushing Strength of Concrete International Journal of Materials Science and Applications Vol 4, No 5, 2015, pp 343349 doi: 1011648/jijmsa19 Abstract: This paper studied the effect of aggregate properties on the crushing strength of concreteThis paper studied the effect of aggregate properties on the crushing strength of concrete In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test And the test results show that concrete made from black stone has the highest workability followed by shingles stone & brick khoa of aggregatesEffect of Aggregate Properties on the Crushing Strength ofProperties of Concrete Blocks — Strength 22 months old, showed crushing strength of 2,530 and 2,610 pounds per square inch These blocks were made of cement 125 parts, lime 05 part, sand and gravel 6 parts, and were tamped from damp mixture It is probably safe to assume that the minimum crushing strength of wellmade blocks, 1 to 5Properties of Concrete Blocks — Strength

This paper presents the fresh and hardened properties of highstrength concrete comprising byproduct fine crushed aggregates (FCAs) sourced from the crushing of three different types of rocks, namely granophyre, basalt, and granite The lowest void contents of the combined fine aggregates were observed when 40% to 60% of natural sand is replaced by the FCAs By the replacement of 40%Properties of Concrete Blocks — Strength In the use of concrete blocks for the walls of buildings, the stress to which they are subjected is almost entirely one of compressionIt is probably safe to assume that the minimum crushing strength of wellmade blocks, 1 to 5, is 1,000 pounds per square inch at 1 month and 2,000 pounds at 1 yearminimum crushing strength of concrete blockThis study focuses on lowdensity foam concrete ranging from 04 to 08 g/cm3 (25 to 50 lb/ft3), with the crushing behavior investigated using a penetration test and dynamic Young’s modulus determined using a resonant frequency test Four distinct crushing phases—linear elastic, transitional, plateau, and final densification—are observedCrushing Behavior and Crushing Strengths of Low
