Ultimate Compressive Strength is defined as the force at which a specimen with a certain cross-section, and consisting of a particular fracturing material, fails when it is subjected to compression. The ultimate compressive strength is normally measured in N/mm2 (force per area) and is thus a stress.

Studies show that high strength GPC can be developed from GGBS and dolomite . Maximum compressive strength was obtained when GGBS and dolomite were mixed in the ratio 70:30 by weight of binder content . To reduce the brittle nature of geopolymer concrete, steel fibres were added at 0.25–0.75% of the volume of concrete .

Mar 31, 2019· Compressive strength is important as it is the main criteria used to determine whether a given concrete mixture will meet the needs of a specific job. Concrete psi. Pounds per square inch (psi) measures the compressive strength of concrete. A higher psi means a given concrete mixture is stronger, so it is usually more expensive.

Rock Mechanics

The compressive strength of the limestone is considerably affected by both processes. In this case, the conversion of limestone to dolomite resulted in an approximately 20 0ecrease in compressive strength whilst the limestone to dolomite to dedolomite conversion resulted in a 75 0ecrease.

Bearing Capacity of Rocks

Dolomite can be used as a substitute for sand in concrete construction. Therefore, this research is conducted on the use of the dolomite material in the construction of concrete. Concrete specimens were made with a mixture proportion of dolomite as a replacement of sand. Then the compressive strength test is conducted.
