Abstract

The invention relates to the technical field of concrete preparation, in particular to concrete containing natural zeolite powder. The concrete is prepared from the following components in parts by mass: 54-81 parts of lightweight sand, 30-56 parts of lightweight aggregates, 38-60 parts of cement, 9-14 parts of zeolite powder, 0.5-2 parts of a water reducer, and 18-28 parts of water. A preparationmethod comprises the following steps: S1, adding lightweight sand, lightweight aggregates, cement and zeolite powder into a stirrer, starting the stirrer to obtain a material mixture; and S2, addingwater and water reducer into the material mixture, continuously stirring for a certain period of time to obtain the concrete containing the natural zeolite powder. The concrete provided by the invention can effectively improve water-retaining property of the concrete, improves viscosity of the concrete, reduces gradual loss of the concrete, and meanwhile guarantees good pumpability performance ofthe concrete, boosts production efficiency, and also effectively relieves dead load, and guarantees structure safety.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, in particular to a concrete containing natural zeolite powder and a preparation method thereof. Background technique [0002] Lightweight aggregate concrete has strict requirements on raw materials, mix ratio and mixing process, and it is difficult to guarantee the stability of its working performance. Severe separation of bones, excessive loss over time, etc. Adding appropriate amount of zeolite powder under the same mix ratio, and properly changing the mixing process of concrete can effectively improve the working performance of concrete and meet various technical requirements. With the vigorous development of the construction market, the supply of waste slag admixtures such as fly ash, mineral powder, and silica fume is in short supply, and there is even no supply of goods, which greatly restricts the normal production of concrete. [0003] Therefore, we propose a concrete conta...
