The 16 in. x 8 in. x 4 in Concrete Block 33 lb. is manufactured to ASTM C 90 specifications and used in foundations and above-grade masonry walls. This heavy weight solid block is uniformly square and free of large chips. These heavy weight interlocking gray blocks are uniform in texture, size and color while being dimensional and accurate.
block Young’s modulus obtained from tests on samples extracted from concrete blocks (Hamid and Chukwunenye 1984). Similarly, tests have been performed in samples extracted from hollow concrete, calcium silicate and solid concrete blocks to identify the compressive and tensile
The strength and durability of these Normal weight Solid blocks make it ideal for construction of heavy load bearing walls and is also economic for acoustic applications. At Emcon, solid blocks are available with a face dimensions of 400 x 200 mm (L x H) and 390 x 190, with varying thickness of 100, 150, 200, 250 and 300 mm.
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 compression. In compressive strength well-made concrete does not differ greatly from ordinary building stone.
on square centimeter will be taken as the compressive strength of the block. The mean of the compressive strength of the three blocks will be taken as the compressive strength of batch compressive strength less than 75% of the mean value so obtained.
Strength, as associated with cmu, is expressed in two distinct values: Cmu compressive strength is the psi calculated from the net area of the individual unit. The minimum average net compressive strength per ASTM C90, as of the 2014 edition, is 2000 net psi.
