Waterborne polyurethane polymer modified concrete for bridge deck slab and preparation method
The invention relates to waterborne polyurethane polymer modified concrete for a bridge deck slab and a preparation method. The waterborne polyurethane polymer modified concrete comprises the following components: ordinary silicate cement, pebbles, medium sand, coal ash, silicon ash, a naphthalene water reducer, waterborne polyurethane emulsion and water. The preparation method comprises the following steps: putting the dried pebbles, the ordinary silicate cement, the medium sand, the coal ash and the silicon ash into a stirring machine at a normal temperature, and stirring; adding the waterborne polyurethane emulsion, and stirring; adding the water, and stirring; finally, adding the naphthalene water reducer, and stirring. The invention provides the waterborne polyurethane polymer modified concrete for problems that an ordinary concrete bridge deck slab is likely to suffer from corrosion damage and low in strength. The polymer modified concrete can effectively solve the problem of high possibility of causing corrosion damage of the bridge deck slab in a complicated environment and greatly reduce the repair expense in an operation process. The polymer modified concrete can be applied to a bridge surface structure which is relatively high in durability requirement or is relatively difficult to repair and relatively large in span.
