Concrete blocks are made from cast concrete, e.Portland cement and aggregate, usually sand and fine gravel for high-density blocks.Lower density blocks may use industrial wastes as an aggregate.It has many advantages, such as durability, strength and structural stability, fire resistance, insulation, sound absorption and economical.
Two blocks 6x8x9 inches, 22 months old, showed crushing strength of 2,530 and 2,610 pounds per square inch.These blocks were made of cement 1.25 parts, lime 0.5 part, sand and gravel 6 parts, and were tamped from damp mixture.It is probably safe to assume that the minimum crushing strength of well-made blocks, 1 to 5, is 1,000 pounds per.
Summary of hollow blocks average strength tests results at 7 days figure 3 shows the variation in the average crushing strengths of each concrete mix at 7 days curing.Compared to the commercial blocks the crushing strength of the blocks, made of recycled materials with no additives g00 dropped to 6.In comparison, a significant.
Fully concrete-filled tubes achieved the lowest values of splitl and iplitl demonstrating a lower drop of the load after the initial peak.Comparing st to the specimens with multiple timber blocks, all three loads are by-and-large the same, although itl and spl of specimens with multiple timber blocks are generally slightly higher than st.
Properties of concrete blocks strength.It is probably safe to assume that the minimum crushing strength of well-made blocks, 1 to 5, is 1,000 pounds per square inch at 1 month and 2,000 pounds at 1 year a block 12 inches wide and 24 inches long has a total surface of 288 square inches, or, deducting for openings, a net area of 192 inch.
