Freezing and Thawing Resistance of Latex Modified Concrete with Latex Content
라텍스 혼입에 따른 LMC의 동결융해 저항특성평가
Abstract
This study was performed to change the latex content for properties of freezing-thawing resistance. When styrene-butadiene latex is added to portland cement, aggregate and water, a concrete with the color, consistency and workability of ordinary conventional concrete results, but with 20% to 35% less water. When cured, the concrete consists of hydrated cement and aggregate interconnected by a film of latex particles. In general, increasing the amount of latex will produce concrete with increased tensile and flexural strength and lower modulus of elasticity. Air entrainment has been used in conventional concrete for the past 50 years to impart freeze-thaw resistance. Latex modified concrete does not need additional air entrainment for freeze-thaw resistance provided adequate cure occurs.
