Hard-Cem is added to the concrete at the time of batching to increase the hardness of the concrete and extend concrete wear life. It outperforms and overcomes deficiencies of labor-intensive surface applied hardeners and is used to enhance the durability of both air-entrained and non-air-entrained concretes.

Cement & Concrete

Cement and Concrete . In its simplest form, concrete is a mixture of paste and aggregates. The paste, composed of portland cement and water, coats the surface of the fine and coarse aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

Tuff Curb Technology | Concrete Edging MN

Air-Entrainment - We add air-entrainment to our concrete. Millions of microscopic air cells per cubic foot. These air pockets relieve internal pressure on the concrete by providing tiny chambers for water to expand into when it freezes. Cable "Re-Bar" Protection - We run a 1/8 inch zinc coated, steel cable through our curb increasing tensile

Concrete Resistance to Sulfates: The Benefit of Admixtures

The purposeful entrainment of air in concrete, using Daravair and Darex air-entraining agents, protects against sulfate attack in the same manner as it protects against freezing and thawing. The air voids provide microscopic expansion chambers for relief of the pressure that is built up in the concrete by the growth of the sulfate crystals.

Daratard® 38 | Resource | GCP Applied Technologies

Daratard 38 is designed for use on jobs where high temperatures make extended setting times desirable. It is recommended only when the primary purpose is to delay and control the setting time of concrete. When time and temperature are not major considerations, water-reducing admixtures from GCP Applied Technologies should be used.

Influence of the Type of Cement and the Addition of an Air

The concrete cover is the basic protection of the reinforcement against the influence of external factors that may lead to its corrosion. Its effectiveness depends mainly on the composition of the concrete mix, including the cement used. Depending on external environmental factors that may aggressively affect the structure, various types of cements and concrete admixtures are recommended.

Admixture Basics: An Overview

Air Void Systems • Discovered in the 1930’s and is still considered one of the most significant improvements in concrete technology. • Most standard specifications require that concrete be air entrained if exposed to freeze thaw cycles. • Uses air entraining admixtures to create a network of small disconnected air voids
