How to Prevent Cracks in Concrete? Causes & Repairs of …

Don''t finish the concrete when there is bleed water on the surface, finishing leads the water back to concrete instead of evaporating thus leading to cracks. Proper Curing of Concrete Stop rapid loss of water from surface or drying of concrete due to hydration (liquid concrete converts to plastic and then to solid state) causes drying of the slab, so it''s recommended to cure the slab for ...

6 Types of Concrete Cracks and What They Mean | …

Since concrete cannot shrink around a corner, stress will cause the concrete to crack from the point of that corner. Plastic shrinkage cracks are typically very narrow in width and barely visible. While nearly invisible, it is important to remember that plastic shrinkage cracks don''t just exist on the surface, they extend throughout the entire thickness of the slab.

Cracked Concrete

 · Control joints help concrete crack where you want it to. The joints should be of the depth of the slab and no more than 2-3 times (in feet) of the thickness of the concrete (in inches). So 4"concrete should have joints 8-12'' apart.

Bleeding of Concrete: Causes, Effect and Ways to Reduce it …

Concrete is a mixture of cement, fine aggregates and course aggregates. Number of problems can occur in concrete due to improper mixing, curing and placing, one such problem is "bleeding" in concrete. BLEEDING in concrete is a phenomenon in which free water in the mix rises up to the surface and forms a paste of cement on the surface known as "laitance" .

Properties of Concrete

 · Bleeding in concrete is sometimes referred as water gain. It is a particular form of segregation, in which some of the water from the concrete comes out to the surface of the concrete, being of the lowest specific gravity among all the ingredients of concrete.

Corrosion of Embedded Materials

Corrosion of Embedded Metals. Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration inconcrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expansion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling.

Control Joints

The blade cuts a joint into the hardened concrete as soon as the surface will not be torn, abraided or damaged by the cutting action. Concrete jointing or grooving tools are metal, about 6 inches long, 3 to 4 inches wide with different length bits ranging from 3/16 of an inch to 1 inch in depth.
