Pumping plastic concrete taking slag as aggregate and preparation method thereof
The invention discloses pumping plastic concrete taking slag as aggregate and a preparation method thereof. According to the present invention, the household garbage incineration slag is adopted as the concrete aggregate, such that the resource utilization of the waste residue is achieved, the slag treatment problem is effectively solved, the problem of the shortage of the sand-gravel material for the concrete is alleviated, the concrete production cost is reduced, and the significant economic benefits and the significant social benefits are provided. Besides, the concrete with the compressive strength and the permeability coefficient meeting engineering requirements can be prepared through the method, so that the concrete has good mechanical performance and anti-seepage performance, and the anti-seepage engineering requirements in the fields of environmental geotechnical engineering, hydraulic engineering and the like are met. The bentonite, the clay and other materials are doped, so that the workability of the concrete is improved, the concrete has good pumping performance and is convenient to construct, and the construction efficiency is improved. In addition, the slag contains a certain cement curing product, has certain gelation activity, and can improve the durability of the concrete and prolong the service life of a project.
本发明公开了一种以炉渣为骨料的泵送塑性混凝土及其制备方法。本发明中，通过将生活垃圾焚烧炉渣作为混凝土骨料，实现了废渣的资源化利用，有效解决了炉渣处理处置难题，同时缓解了混凝土用砂石料紧缺问题，降低了混凝土生产成本，具有显著的经济效益和社会效益。此外，该方法可以制备出满足工程要求的抗压强度和渗透系数的混凝土，使其具有良好的力学性能和防渗性能，满足环境岩土工程和水利工程等领域的防渗工程需求。掺入了膨润土、粘土等材料，改善了混凝土的和易性，使其具有良好的泵送性能，方便施工，提高了施工效率。此外，炉渣中含有一定的水泥熟化产物，具有一定的胶凝活性，可以提高混凝土的耐久性，延长工程使用寿命。
