lab concrete proportioning mixing and testing

Enter a virtual engineering lab to test concrete materials and work with an engineer. In the lab you will find samples of fine and coarse aggregates, cement, water, and admixtures. Freely test many combinations of these materials in order to provide the recipe for a durable concrete to a team of construction workers.

For testing the compressive strength of concrete, cylindrical test specimens of size 4 ´ 8-inch (100 ´ 200-mm) or 6 ´ 12-inch (150 ´ 300-mm) are cast and stored in the field until the concrete hardens in accordance with the requirements of ASTM C 31, Standard Practice for Making and Curing Concrete Test Specimens in the Field.

Note 1: The concrete test results for concrete specimens made and cured using this practice are widely used. They may be the basis for acceptance testing for project concrete, research evaluations, and other studies. Careful and knowledgeable handling of materials, mixing concrete, molding test specimens, and curing test specimens is necessary.

Proportioning of concrete is the process of selecting quantity of cement, sand, coarse aggregate and water in concrete to obtain desired strength and quality. The proportions of coarse aggregate, cement and water should be such that the resulting concrete has the following properties: When concrete is fresh, it should have enough workability so that it can […]

An accurate determination of mix proportions by using computer data is usually not possible as the materials used are essentially variable and their properties are not assessable quantitatively. Concrete Mix Design is an extremely flexible building material which can be exclusive designed for strength that may range from M10 to M100.

The only work done on-site is to make a concrete cylinder for the compression test. The strength is measured in Megapascals (MPa) and is commonly specified as a characteristic strength of concrete measured at 28 days after mixing. The compressive strength of concrete is a measure of the concrete's ability to resist loads which tend to crush it.
