Effect of moisture on the physical and durability properties of methyl methacrylate polymer concrete
The compressive strength of methyl methacrylate PC composites decays very rapidly as the moisture content of the coarse aggregate is increased from 0 to 1 wt %. The durability of the PC also shows evidence of decay. Addition of silane coupling agent, such as A-1120, to the monomer component of a PC composite increases the compressive strength of such composites made with moist coarse aggregates. The compressive strengths of such PC composites are as high as a normal PCC used in highway applications. The durability of PC composites made with a silane additive seems to increase as the composite undergoes freeze-thaw cycling which reinforces the justification that such materials can be used for PCC repairs without a sacrifice in use lifespans. However, for the convenience of using moist aggregates, one must endure the additional cost of the silane coupling agent. If it costs more than $0.02/lb to dry the aggregate, and one is willing to accept the reduced strengths associated with moist aggregates, then the use of a silane coupling agent can be cost effective. 3 figures, 4 tables.
