Effect Of Aggregate Volume Fraction On The Elastic Moduli And Void Ratio Of Cement-Based, Shih-Wei Cho, Chung-Chia Yang, Ran Huang Jun 2000

Effect Of Aggregate Volume Fraction On The Elastic Moduli And Void Ratio Of Cement-Based, Shih-Wei Cho, Chung-Chia Yang, Ran Huang

Journal of Marine Science and Technology

The effects of aggregate volume fraction on the void ratio and the elastic modulus of mortar were studied. Cylindrical specimens with six volume fractions (a/t = 0., 0.05, 0.1, 0.2, 0.3, and 0.4) of fine aggregate and various water/cement ratios (w/c = 0.3, 0.4, and 0.5) were cast and tested. Double inclusion model for three-phase composite (matrix, aggregate, and void) was used to predict the volume of total void based on the properties and quantities of the components and composites. Based on this study, when higher volume fraction of aggregate is used in the mix, the elastic modulus of the …

The Effect Of Aggregate Volume Ratio On The Elastic Modulus And Compressive Strength Of Lightweight Concrete, Chung-Chia Yang, Yung-Shin Yang, Ran Huang

Journal of Marine Science and Technology

In order to investigate the effect of aggregate volume ratio (S/A, volume of sand/ volume of total aggregate) on the elastic modulus of lightweight concrete, cylindrical specimens ( 010x200mm) with different S/A ratios and various water-cement ratios were cast and tested. Both single inclusion model and double inclusion model were applied to predict the elastic moduli of two-phase and three-phase cement-based composite materials, respectively. The elastic modulus of lightweight aggregate was obtained based on composite theory models. In this study, the aggregate volume ratio significantly affects the elastic properties of lightweight concrete. The elastic modulus and compressive strength of lightweight …
