As every civil engineer knows, Portland Cement is the most versatile and important material of construction, and will probably remain so far into the future. Yet few books, if any, exist that offer an in-depth analysis of the mixing and testing methods of this vital hydraulic cement. This statement, written about the first edition of Engineered Mix Design and Test

If the concrete is placed in the work, report both tests on the Weekly Concrete Report (Form 2448) with a notation of the amount of water, cement or air-entraining admixture added. The number of revolutions at mixing speed shall not exceed 150 per Specification 2461.4C. Mix the concrete at agitating speed for all revolutions over

Mar 01, Typically the speed for mixing is 1.57 (15 rpm), while the transport of pre-mixed concrete uses only 0.2 (2 rpm) to 0.6 (6 rpm) In the United States, most ready-mixed concrete is mixed in trucks and not pie-mixed in a plant. In a tilting drum mixer (Fig. 3), the inclination can be
