Jan 27, 2010 It is the character of this surface that makes hydrated cement an effective cementing agent and provides the versatility of concrete in forming bodies of high strength and almost any desired shape. When surfaces are very close to each other there
Mar 31, 2019 Terminology Concrete strength properties and why they are important Compressive strength of concrete. This is the most common and well-accepted measurement of concrete strength to assess the performance of a given concrete mixture. It measures the ability of concrete to withstand loads that will decrease the size of the concrete.
Workability of concrete is measured in terms of the ease of mixing and placing of concrete. Highly workable concrete can easily be mixed, placed and transported. All the materials and processes involved in producing concrete affect the workability of concrete. Factors Affecting the Workability of Concrete

Compressive strength depends on a number of factors wc, cement content, type of aggregate, curing, age, ambient conditions, and specimen geometry. ... The wc is the single most important factor governing the strength of concrete. High wc implies high porosity, and thus lowered strength. ... crushing of concrete at the grips may occur ...
High-strength concrete is specified where reduced weight is important or where architectural considerations call for small support elements. By carrying loads more efficiently than normal-strength concrete, high-strength concrete also reduces the total amount of material placed and lowers the overall cost of the structure.
Concrete compressive strength for general construction varies from 15 MPa 2200 psi to 30 MPa 4400 psi and higher in commercial and industrial structures. Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during the production of concrete, etc.
Jan 24, 2019 Strength . One of the most important factors before ordering ready-mix concrete is knowing the required compressive strength.Typically, reinforced concrete ranging between 3,500 to 4,000 psi is used on footing and slabs on grade between 3,500 to 5,000 psi on suspended slabs, beams and girders and walls and columns normally require between 3,000 to 5,000 psi.
Jul 07, 2016 Compressive Strength. The compressive strength of any material is defined as the resistance to failure under the action of compressive forces. Especially for concrete, compressive strength is an important parameter to determine the performance of the
Compressive strength of cement concrete is the strength of concrete against crushing due to direct compressive load. It is considered to be the most important property of concrete and is often taken as the index of the overall quality of the concrete. Factors Affecting Compressive Strength of Concrete.
