Hydraulic Cement - an overview ScienceDirect Topics

Hydraulic-Cement Grouting. Hydraulic-cement grouting is a common method of repairing cracks in concrete that is most often used in dormant cracks. This type of grouting tends to be less expensive than chemical grouts, and is well suited for large volume applications. However, the grouting is subject to pressure and may not fill a crack entirely.

Will hydraulic cement bond to concrete?

However, hydraulic cement has a weak bond with concrete, which is the reason the crack needs an inverted V-groove to hold it in. Additionally, hydraulic cement is very rigid. Hydraulic cement is generally used for patching water-related cracks and holes in concrete, but it also makes a good patching alternative for any type of cement repair.

Definition of concrete, hydraulic cement, mortar, and grout

A. Concrete is a composite material that consists of a mixture of hydraulic cement, aggregates, and water, with or without admixtures, fibers, or other cementitious materials. Hydraulic cement is cement that sets and hardens by chemical reaction with water (hydration)
