Mortar for concrete having polyurethane foam and method of thereof
Abstract:
Disclosed are a mortar for concrete mainly consisting of urethane foam and a method for manufacturing the same, in which urethane foam and Styrofoam used as insulating materials for household electronic appliances and a pre-cast panel are not discarded, but recycled such that the urethane foam and the Styrofoam are mixed with concrete in the construction of flooring of apartments or an ondol of houses. Low weight structure, superior sound-absorption effect and heat insulation effect can be obtained, and cracks are prevented from being generated in the constructed part. Construction work is simplified, and economical efficiency is enhanced. Collected waste urethane foam and waste Styrofoam are pulverized into a size of 1 to 10 mm using a pulverizer. The pulverized urethane foam and Styrofoam are mixed to each other to form urethane foam. Admixture is added to the urethane foam, and then cement and water are mixed with the urethane foam in a predetermined ratio to form a lightweight insulating urethane foam concrete mortar using a mixer and a truck mixture. The lightweight insulating urethane foam concrete mortar is manufactured and is transported from a mixing area to a construction part such that materials of the concrete is prevented from being separated from each other. The concrete is poured using squeezing equipment and hydraulic transfer equipment and then cured for a predetermined curing time to prevent sudden change in the temperature.
