A concrete slab is found to have a characteristic strength of 28 N/mm“ and density of 2350 kg/m from on-going cube data. The prescribed grade is 30N. One truckload of concrete is suspected of non-compliance due to a colour variation. The location of the suspect batch is known but no cubes are available. Core sampling is requested by the Client on the suspect concrete. The minimum acceptable In-situ Cube Strength was set at 20.0 N/mm? (i.e. 30/1.5) during a planning meeting before cores were agreed to be taken.

Concrete is required for several structural members of a residential house. Due to the present moisture, it is expected that the concrete shall be non-aerated (Non AE) with a 28 day compressive strength of 3.000 psi for slabs and 4,000 psi for beams and columns. Due to extra moisture present in the site, the slump to be used shall be the minimum allowed by the ACI mix. Using a 3/4 inch max aggregate size, compute for the weight of cement, water coarse aggregate, and fine aggregate. Aggregate details: Cement: Type 1.
