Freeze-Thaw Resistance - cement.org

Concrete with a low permeability (that is, a low water-cement ratio and adequate curing) is better able to resist freeze-thaw cycles. In rare cases, air-void clustering can occur, leading to a loss of compressive strength.

Improvement of Strength of Soil-Cement With Additives

(1 percent) a higher percentage of strength increase (50 percent) was obtained. Con­ tinued study by Le Tellier and Wagner (1955) showed that considerable increase of strength could be effected on silt plus portland cement. In 1955 a thorough review and investigation of the improvement of soil-cement with additives was undertaken.

Types of Chemical Admixtures - The Concrete Network

Chemical admixtures are used to improve the quality of concrete during mixing, transporting, placement and curing.

Cement Chemistry and Additives - Schlumberger

Cement evaluation logs and other cased-hole logs can indicate the strength of the set cement and whether it "s bonded to the cas.ng (far right). The out- come of a cementing job, however, depends ultimately on choosing the appropriate cement and additives to cope with particu lar well conditions. . Portland cement was developed by Joseph Aspdin

Types of Admixtures of Concrete & Cement | Chemical, Mineral

Pozzolans are commonly used as an addition (the technical term is "cement extender") to Portland cement concrete mixtures to increase the long-term strength and other material properties of Portland cement concrete and in some cases reduce the material cost of concrete. Examples are. Fly ash. Silica Fume. Rice Husk Ash. Metakaolin. Pozzolanic ...

Concrete strength. Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below. First, though a couple of definitions may be useful: The processes of 'setting' and 'hardening' are often confused: Setting is the stiffening of the concrete after it has been placed. A concrete can be 'set' in that it is no longer fluid, but it may ...

Concrete - Wikipedia

Concrete, usually Portland cement concrete (for its visual resemblance to Portland stone), is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently in the past a lime-based cement binder, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or Portland ...

Seven Must-Use Concrete Admixtures (Additives)

Consequently, concrete containing a water-reducing admixture needs less water to reach a required slump than untreated concrete. The treated concrete can have a lower water-cement ratio. This usually indicates that a higher strength concrete can be produced without increasing the amount of cement.
