The effects of aggregate gradation, amount, and size on pervious portland cement concrete (pcc) static modulus of elasticity were compared using four different mixtures. A standard mix and three variable mixes using a uniform gradation, increased aggregate amount, and increased aggregate size were used. The effective air void content was determined for each mixture.
Relation between dynamic young's modulus of elasticity and flexural strength of cemented base materials. O x 10 psi; in the case of soil-cement made from silty sand, type b, the variations were produced by changing the dry density, cement content, moisture content and age of test.

A portland cement concrete designed to have 28-day compressive strength of 6,000 psi (41 mpa) was used as a control concrete. Concrete mixes were also designed to have fly ash substitution based on total cement weight in the range of 0 to 60% by weight.

Comparing acrylic stucco and traditional stucco is a good thing to talk about because there is a lot of confusion about the topic, due to a number of different things like multiple names for both types, different materials that are used, the price of the material and the labor involved you get the picture.
Tensile strength - σ 2 - 5 mpa (300 - 700 psi); modulus of elasticity - e 14 - 41 gpa (2 - 6 x 106 psi).
An experimental investigation was carried out to determine the dynamic modulus of elasticity of pozzolana portland cement concrete. Large numbers of concrete cubes were prepared in the laboratory.
Therefore, knowledge of the modulus of elasticity of high strength concrete is very important in table 2 properties of chemical admixture-hyper plasticizer hyper plasticizer ( hp ) – classic superflo portland cement association.
Jul 1, 2008 of transportation decided to use portland cement as stabilization agent. Classical mohr-coulomb, griffith crack theory, modified griffith crack determine the cohesion and modulus of elasticity of lime treated soils.
Modeling the linear elastic properties of portland cement paste. This article focuses on computing the elastic moduli of cement paste at the micrometer scale by accounting for all the microstructure at that scale, yet treating the calcium-silicate-hydrate phase as an elastically homogeneous phase.
The multi-scale modeling of portland cement paste is addressed to predict simultaneously its stiffness and its effective diffusion coefficient of chloride ions. The heterogeneity of cement paste is handled thanks to a hierarchy of eshelby-based homogenization schemes within the framework of micromechanics.
This reference could have been ignored (missed) since the classical cement modulus of elasticity is lower than that of portland cement concrete (about 80%).

Relationships are proposed to estimate the tensile strength and modulus of elasticity based on the compressive strength of alkali-activated concrete, which are of the same form as those currently employed for portland cement concrete.
