Bridge deck slab waterborne polyurethane polymer concrete and preparation method thereof
The invention provides bridge deck slab waterborne polyurethane polymer concrete and a preparation method thereof. The bridge deck slab waterborne polyurethane polymer concrete comprises the following raw material components: coarse aggregate, medium sand, coal ash, silica dust, a naphthalene water reducer, waterborne polyurethane and a silane coupling agent. The preparation method of the bridge deck slab waterborne polyurethane polymer concrete comprises the following steps: at room temperature, putting dried coarse aggregate, medium sand, coal ash and silica dust into a stirrer; then, adding waterborne polyurethane emulsion and stirring; and then adding the silane coupling agent and stirring; and finally adding the naphthalene water reducer and stirring. According to the preparation method, the waterborne polyurethane polymer is used for replacing concrete to serve as a cementing material, is mixed with aggregate and is added with coal ash, silica dust, the naphthalene water reducer and the silane coupling agent. The bridge deck slab waterborne polyurethane polymer concrete can be applied to a bridge deck structure which has a high requirement on durability or is difficult to repair and large in span.
