What are Concrete Additives? Why do we use them? Big D

Feb 02, 2018 The additives are added to a water-cement mixture to increase the life of the concrete, control setting, and hardening and fix the general concrete behavior. They can be powdered or liquid additives. The additives can be added at the manufacturing point, or at the job site. At Big D Ready Mix, we ensure we follow the best concreting and batch

Cement Production an overview ScienceDirect Topics

G. Habert, in Eco-efficient Construction and Building Materials, 2014 10.1 Introduction. Cement production has undergone tremendous developments since its beginnings some 2,000 years ago. While the use of cement in concrete has a very long history (Malinowsky, 1991), the industrial production of cements started in the middle of the 19 th century, first with shaft kilns, which were later

Concrete

Concrete production is the process of mixing together the various ingredients—water, aggregate, cement, and any additives—to produce concrete. Concrete production is time-sensitive. Once the ingredients are mixed, workers must put the concrete in place before it hardens. In modern usage, most concrete production takes place in a large type

How concrete block is made material, manufacture, used

The production of concrete blocks consists of four basic processes: mixing, molding, curing, and cubing. Some manufacturing plants produce only concrete blocks, while others may produce a wide variety of precast concrete products including blocks, flat paver stones, and decorative landscaping pieces such as lawn edging.

Concrete Sika

Concrete. Sika develops and markets a complete range of admixtures and additives for use in concrete, cement and mortar production. These products enhance specific properties of the fresh and hardened concrete, such as workability, watertightness, durability, or early and final strength. The demand for admixtures and additives is currently on

lightweight concrete Post-war building materials

Lightweight concrete is a collective term for different types of concrete which are all characterized by a low specific weight. The reduced density is achieved by adding specific ingredients to the mixture or by means of special production techniques, resulting in a weight decrease from 2.000 or 2.500 kg/m³ for ‘ordinary’ concrete to approx. 500 []
