Calcareous sand concrete novel embankment construction method
The invention discloses a calcareous sand concrete novel embankment construction method. The ratio of each component of calcareous sand concrete is as follows: the dosage of calcareous sand is 600kg/m<3>, the dosage of reef limestone macadam is 750kg/m<3>, the dosage of cement is 700kg/m<3>, the dosage of the water is 230kg/m<3>, the dosage of the fly ash is 80kg/m<3>, and the dosage of a water reducing agent is 4kg/m<3>. Before construction, a test block is manufactured to control the quality of concrete. According to the invention, the reef limestone macadam and calcareous sand on the islandreef are utilized and mixed with an admixture according to a certain mixing ratio to form the calcareous sand concrete for constructing embankments on islands and reefs, materials are easy to obtain,limited resources of the islands and reefs can be effectively utilized, the transportation cost of land source materials can be reduced, the engineering construction period can be shortened, and themethod has very important scientific significance and engineering value for popularization and application of new building materials and island and reef engineering construction development.
本发明公开了一种钙质砂混凝土新型路堤施工方法，其中钙质砂混凝土的各组分配比为：钙质砂用量为600kg/m3、礁灰岩碎石用量为750kg/m3、水泥用量为700kg/m3、水用量为230kg/m3、粉煤灰掺量为80kg/m3、减水剂掺量为4kg/m3，施工前制作试块对混凝土的质量进行控制，本发明利用岛礁上的礁灰岩碎石和钙质砂，与掺料按一定配合比拌和，形成一种钙质砂混凝土用于岛礁上路堤建设，其取材容易，不仅能够有效利用岛礁有限的资源，还能降低陆源材料的运输成本，缩短工程建设周期，对于建筑新材料的推广应用和岛礁工程建设开发均具有很重要的科学意义和工程价值。
