Introduction
Ordinary cement products in the life of some chemical etching conditions is relatively short, which is Portland cement concrete chemical resistance is not
Good about. Alkali slag and fly ash concrete is composed of a large number of fly ash, slag and other industrial wastes, alkaline activator, special admixtures and gravel aggregate
The basic composition of the excitation concrete, Portland cement concrete and different, it has a strong salt, acid, alkali corrosion, for the manufacture of corrosion
Eclipse cement products, after twenty years of research and development, the country has more than a dozen companies producing corrosion-resistant concrete drainage pipes and corrosion-resistant concrete
Poles and other products. Such corrosion-resistant concrete products and concrete products compared with the general decay ability, corrosion resistance and good overall, and
Stiffness than the plastic products, low cost, energy saving and environmental protection in line with the requirements of good prospects for development, has been used in sewage treatment works, coastal and western
Saline corrosion areas. In order to meet the requirements of the quality and durability of concrete products, China Building Materials Industry Association made a timely manner "for resistance
Corrosion products of alkali-activated slag cement fly ash concrete "national standards project plan to standardize our raw corrosion resistant concrete products
Production, use, sale, quality and the promotion of corrosion-resistant concrete products, production development and technological progress.
Cement products for corrosion-resistant base slag powder
Ash concrete
1 Scope
This standard specifies the products for corrosion resistant cement alkali slag and fly ash concrete (hereinafter referred to as slag and fly ash concrete base) terms
And definitions, classification, raw materials, technical requirements, test methods, inspection rules, storage and transportation and other content.
This standard is applicable to acid, alkali, corrosion-resistant cement products using alkali slag and fly ash concrete in salt environment.
