a concrete or a mortar having synthetic rubber latex and Waterproof paving method using the concrete and the mortar

摘要

PURPOSE: Provided is a water proof mortar or concrete, applied to roads, bridges and walls, which improves durability of construction, bonding strength between water proof materials and concrete construction, and saves maintenance costs by mixing synthetic rubber, latex, with concrete. CONSTITUTION: The concrete composition comprises 5-6wt.% of SBR latex, 16-20wt.% of cement, 43-47wt.% of sand, 23-26wt.% of gravel and 6-8wt.% of water. The mortar composition comprises 1-4wt.% of SBR latex, 20-23wt.% of cement, 67-69wt.% of sand and 6-7wt.% of water. The SBR latex contains 58.3wt.% of styrene, 6wt.% of butadiene, and a small amount of non-ionic surfactant, anion surfactant and potassium persulfate. The paving method of concrete or mortar is as follows: preparing latex-contained concrete or mortar; applying the prepared concrete or mortar to roads, bridges and walls; casting in place; finishing and curing.
