Eq. 2 is the cumulative Weibull distribution with scale parameter and shape parameter ; = [^ ()] = constant factor depending on the structure geometry, = structure volume; = relative (size-independent) coordinate vectors, ^ = dimensionless stress field (dependent on geometry), scaled so that the maximum stress be 1; = number of spatial ...
Mass concrete is defined by American Concrete Institute Committee 207 as "any volume of concrete with dimensions large enough to require that measures be taken to cope with the generation of heat from the hydration of cement and attendant volume change to minimize cracking."

SUREROAD, another 32.5N product, is a custom-made cement meant for road construction and 4. SUREWALL, is a 22.5X masonry cement specifically designed for plastering and brick ...
As per Indian codes, compressive strength of concrete is defined as: Field cured concrete in cubic steel molds (Greece) The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested after 28 days (fck). In field, compressive strength tests are also conducted at interim duration i.e ...
Regular concrete is the lay term for concrete that is produced by following the mixing instructions that are commonly published on packets of cement, typically using ...
Cement board is composed of aggregated Portland cement with a glass-fiber mesh on the surfaces. This 5 ⁄ 16 inch (7.9 mm) thick cement board is designed as an underlayment for tile floors. These are 3-by-5-foot (91 by 152 cm) sheets.
Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]
Consider a beam whose cross-sectional area increases in two dimensions, e.g. a solid round beam or a solid square beam. By combining the area and density formulas, we can see that the radius of this beam will vary with approximately the inverse of the square of the density for a given mass.
