10 Properties of Concrete and their Uses Properties of concrete are influenced by many factors mainly due to mix proportion of cement, sand, aggregates and water. Ratio of these materials control the various concrete properties which are discussed below.
Concrete - Wikipedia
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (for its visual resemblance to ...
Types of Concrete & Characteristics | Concrete …
The concrete in which common ingredients i.e. aggregate, water, cement are used is known as normal concrete.It is also called normal weight concrete or normal strength concrete. It has a setting time of 30 - 90 minutes depending upon moisture in atmosphere, fineness of cement etc.

4-1-2013 · Characteristic strength of concrete is one of the important properties of concrete which indeed unanimously by design engineer or any other person involved in the construction sector. The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days (fck)- as per Indian Standards (ACI…
Properties of concrete - Wikipedia
Concrete has relatively high compressive strength (it doesnt crack under weight), but significantly lower tensile strength (it cracks when being pulled). The compressive strength is typically controlled with the ratio of water to cement when forming the concrete, and tensile strength is increased by additives, typically steel, to create reinforced concrete.

Aggregates - cement.org
Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.
Properties of Concrete - ce.memphis.edu
Properties of Concrete Concrete is an artificial conglomerate stone made essentially of Portland cement, water, and aggregates. Properties of Concrete While cement in one form or another has been around for centuries, the type we use was invented in 1824 in Britain. It was named Portland cement because it looked like the

characteristics. By changing the relative proportions of these components, cement manufacturers can control the properties of the product. The primary product of cement hydration is a complex and poorly crystalline calcium-silicate-hydroxide gel (or CSH). A secondary product of hy-dration is calcium hydroxide, a highly crystalline ma-terial.
