  • Testing of Concrete Blocks Civil Engineering

    Testing of Concrete Blocks Civil Engineering

    Concrete can be converted into precast masonry units such as Hollow and Solid normal and light weight concrete blocks of suitable size to be used for load and nonload bearing units for wallings. Use of such concrete blocks are more appropriate in region where soil bricks are costly, poor in strength .

    Properties of concrete Wikipedia

    Properties of concrete. In very highstrength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength. In lean concretes (with a high watercement ratio) the crushing strength of the aggregates is not so significant.
