Concrete Lab Report

    Experimental Methods Provide a brief description of the five mixes that were produced and tabulate the mixture proportions (use kg/m3 rather than the actual masses used for the batch) – you should be able to fit all five mixes in one table as shown below: Mix # 1 Mix # 2 Mix # 3 Mix # 4 Mix # 5 Mix # 6 Portland Cement (kg/m3 ) Fly Ash (kg/m3 ) Silica Fume (kg/m3 ) Water (kg/m3 ) Initial W/CM Stone (kg/m3 ) Sand (kg/m3 ) AEA (mL/100kg) WRA (mL/100kg) Initial Slump (mm) Water added (kg/m3 ) HRWR added (mL/100kg) Final slump (mm) Air (%) Final W/CM Explain how the initial slump was measured and then that either water or a high-range waterreducing (HRWR) admixture was added to achieve a target slump in the range of 200 ± 25 mm Give details on the specimens that were produced from each mix and how they were stored after casting (see lab handout) – include details of the temperature of storage.   Describe the testing that was performed on the hardened concrete specimens
