Concrete or Cement?

The question many are asking is this: what is the difference between concrete and cement? The cement powder is a key ingredient in concrete. Concrete is the final product.

Concrete in cold temperature

The Contractor is responsible for the protection of concrete when outside temperature fall below 5°C.  It is imperative to prevent the concrete from freezing.

Concrete in hot temperature

The concrete develops it's maximum strength when maturing between 10°C and 35°C and this condition is especially important during the early days. On days when temperatures exceed 27°C, the granular bed should be moistened before concrete placement. The top of slab should be protected from drying too rapidly due to the sun, wind and heat through a water cure.

Water Cure

The water cure is a process that allows the concrete to maintain the humidity and suitable temperature for a defined period (between 3 and 7 days). It allows the concrete to develop the required properties such as durability, waterproofing, resistance to compression and wear resistance, dimensional stability, resistance to freezing and thawing and deicing salts. "A slab of concrete which has been drying too quickly develops a surface with low resistance to wear and abrasion. Proper curing reduces the problems of dust surfaces, chipping, crazing and cracking. From the Techno-# 8 Concrete Technical Bulletin published by the Association Béton Québec.

Why apply a sealer?

The sealer will reduce the dust on the surface. It is recommended to refresh the sealer regularly, according to wear.
