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 wellmade concrete does not differ greatly from ordinary building stone. It is difficult to find reliable records of tests of sand and ...
Even though the commonly accepted minimum Indiana Limestone compressive strength value is 4,000 psi [Indiana University], the designers were more likely to use the 2,000 psi concrete design value available from the anchor manufacturers.
The concrete constituents shall conform to the applicable ASTM Standards. Minimum compressive strength shall be 4,000 psi. • Maximum watercementitious ratio of specified. • A typical precast wetcast mix has a w/c ratio of – • A typical precast drycast mix has a .

This test method covers determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. It is limited to concrete having a density in excess of 800 kg/m 3 [50 lb/ft 3].
Weaver Consultants Group offers construction materials testing (CMT) and inspection services including statecertified laboratories located in Griffith and South Bend, Indiana. What sets us apart is our effort to understand our clients' needs, and our intent to provide a sensible scope of testing.
For this to become a realistic option for concrete plants, it is important that the wash water does not decrease the compressive strength of concrete, otherwise the cost of additional cementitious materials to offset the compressive strength decrease will outweigh any financial benefit of recycling the wash water. ...
