Preparation and application of high-adsorbability machine-made sand concrete
The invention discloses preparation of high-adsorbability machine-made sand concrete, which comprises the following steps: A, crushing high-adsorbability gneiss and diatomite through a jaw crusher, and screening the crushed particles through a continuous screening device to obtain coarse aggregate with the particle size of less than 15mm for later use; b, further crushing the crushed and screened gneiss and diatomite with particles smaller than 15mm for later use; c, uniformly mixing gneiss and diatomaceous earth according to the ratio of 1: 1 and the particle size of less than 15mm for later use, and uniformly mixing gneiss and diatomaceous earth according to the ratio of 1: 1 and the particle size of less than 5mm for later use; and D, adding gneiss, diatomite, ardealite, cement, water and an additive into a mixing device, uniformly mixing, and then carrying out pouring, molding, demolding and standard curing to prepare the high-adsorbability concrete. The high-adsorbability coarse aggregate and the high-adsorbability fine aggregate are added into the concrete raw materials, so that the adsorption force between the concrete raw materials is increased, and the adsorbability of the concrete is improved.
本发明公开了高吸附性机制砂混凝土的制备，包括以下步骤：A、高吸附性的片麻岩和硅藻土通过鄂式粉碎机进行粉碎，将粉碎后的颗粒通过连续性筛选装置筛选出粒径小于15mm的粗骨料，待用；B、将粉碎筛选小于15mm颗粒的片麻岩和硅藻土进一步粉碎，待用；C、将片麻岩：硅藻土为1:1的粒径小于15mm混合均匀，待用，将片麻岩：硅藻土为1:1粒径小于5mm混合均匀，待用；D、片麻岩和硅藻土、磷石膏、水泥、水、外加剂加入到混合装置中混匀，然后进行浇筑、成型、脱模和标准养护，制备得到高吸附性混凝土。本发明通过向混凝土原料中添加高吸附性的粗骨料和细骨料来增加混凝土原料间的吸附力，以增大混凝土的吸附性。
