1/4/2001 · In the United States, most ready-mixed concrete is mixed in trucks  and not pre-mixed in a plant. In a tilting drum mixer ( Fig. 3 ), the inclination can be varied. When the drum is almost horizontal (inclination ≈ 0°), more energy is provided to the concrete because more concrete is lifted to the full diameter of the drum before dropping.
Sprayed concrete is the method by which concrete is sprayed into place, rather than the more conventionally used pouring or placing into formwork . According to the Sprayed Concrete Association other terms used include Gunite, Shot Concrete and Shotcrete. There are many applications and uses for sprayed concrete.

In this experiment, students determine how different sized materials with binder increase the stability and strength of mortar and concrete. Also, students can test how altering the proportions of cement, water and different aggregates affects concrete's properties.
Concrete aggregates should confirm to specified values as per standard specification. The quality of concrete is affected by different physical and mechanical properties of aggregate, i.e. shape, grading, durability, specific gravity and water absorption etc. these properties of aggregated should be tested before using it for concrete production.
