摘要： PROBLEM TO BE SOLVED: To provide a cement mixture which is capable of being used as a solidifying material for constructing or refilling the ground relating to the foundations of a structure and which, even when it contains a relatively large amount of demolished concrete debris of an unadjusted particle size distribution, is easy to administer compressive strength and fluidity and stable in workability and quality and to provide a method for producing the same.
SOLUTION: The cement mixture contains at least demolished concrete debris, water, swellable bentonite, and cement. The method for producing the cement mixture comprises step 1 of forming bentonite water containing swollen bentonite by mixing water with swellable bentonite, leaving the mixture for a definite time, step 2 of forming a cement bentonite slurry by mixing the bentonite water formed in step 1 with water, and step 3 of mixing the cement bentonite slurry formed in step 2 with demolished concrete debris lumps crushed to a specified or smaller particle diameter.

解决方案：水泥混合物至少含有被破坏的混凝土碎屑，水，膨胀膨润土和水泥。制备水泥混合物的方法包括步骤1：通过将水与可膨胀膨润土混合形成膨润土膨润土，通过将步骤1中形成的膨润土水与步骤1中形成的膨润土水混合形成水泥膨润土浆料水和步骤3，将步骤2中形成的水泥膨润土浆料与破碎的具体或更小粒径的混凝土碎屑块混合。版权所有（C）2009，JPO＆INPIT
