Pore Structure and Permeability of Cementitious Materials Containing a Carboxylic Acid Type Hydrophobic Agent

نویسندگان

چکیده

Integral hydrophobic treatment is the most effective method to prolong service life of concrete by resisting transport water containing aggressive ions. The hydrophobicity phenomenon cementitious materials with carboxylic acid type admixture has been presented, and experimental studies, including adsorption, amount hydration products, pore system, are conducted reveal mechanism. It reported that present excellent resistance ability, results nitrogen adsorption isotherm show addition increases volume surface area cement pastes. In addition, fractal geometry theory applied relation between structure permeability coefficient pastes a agent. conclusion, high tortuosity dimension result in when system mixed new admixture.

EFFICIENCY FACTOR OF SUPPLEMENTARY CEMENTITIOUS MATERIALS: A STATE OF ART

The use of supplementary cementing materials is gradually increasing due to technical, economical, and environmental benefits. Supplementary cementitious materials (SCM) are most commonly used in producing ready mixed concrete (RMC). A quantitative understanding of the efficiency of SCMs as a mineral admixture in concrete is essential for its effective utilisation. The performance and effective...

Carboxylic Acid Structure and Chemistry

Carboxylic acids are hydrocarbon derivatives containing a carboxyl (COOH) moiety. Recall that carbon has four valence electrons and therefore requires four electrons or bonds to complete its octet. Based on this valence and bonding order, carbon forms four bonds in its neutral state, and these may be four single bonds or combinations of single and multiple bonds. Oxygen has six valence electron...
