the workability of concrete was determined using slump and inverted slump freshly mixed fiber reinforced concrete was placed in the moulds and consolidated by a vibrating table. Then, each of the specimens was allowed to stand for 24 h before demoulding, afterward stored in water at 23 ± 1 ºC until the time of testing.
ASTM''s plastics standards are instrumental in specifying, testing, and assessing the physical, mechanical, and chemical properties of a wide variety of materials and products that are made of plastic and its polymeric derivatives.
The American Concrete Institute (ACI) is a leading authority and resource worldwide for the development and distribution of consensusbased standards, technical resources, educational programs, certification programs, and proven expertise for individuals and organizations involved in concrete design, construction, and materials, who share a commitment to pursuing the best use of concrete.
The capacity of concrete is reported in psi – pounds per sq. inch in US units and in MPa – mega pascals in SI is usually called as the characteristic compressive strength of concrete fc/ fck. For normal field applications, the concrete strength can vary from 10Mpa to 60 Mpa.

The volume of air in an HMA pavement is important because it has a profound effect on longterm pavement performance. An approximate "ruleofthumb" is for every 1 percent increase in air voids (above 67 percent), about 10 percent of the pavement life may be lost (Linden et al., 1989 [1]).Keep in mind that this ruleofthumb was developed using limited project data, should be used with ...

Aug 01, 2015· Cement testing 1. 1 Short Notes of Cement Chemistry NARENDRA KUMAR KANCHKAR Quality Controller(Cement) Cement History: Joseph Aspdin took out a patent in 1824 for "Portland Cement," a material he produced by firing finelyground clay and limestone until the limestone was calcined.
Concrete made with GGBS cement sets more slowly than concrete made with ordinary Portland cement, depending on the amount of GGBS in the cementitious material, but also continues to gain strength over a longer period in production conditions. This results in lower heat of hydration and lower temperature rises, and
