Machine-made sand for premixed concrete and production process of machine-made sand
The invention relates to the technical field of materials for premixed concrete, and discloses machine-made sand for premixed concrete, the machine-made sand comprises a common sand material, a reinforced sand material and an additive, the common sand material is composed of sandstone, quartz sandstone, slag and tailings, the reinforced sand material is composed of granite, basalt, rhyolite and limestone, and the additive is added into the common sand material. The additive is composed of a main functional raw material and an additional functional raw material, and the additive composed of the main functional raw material and the additional functional raw material is added into a common sand material and a reinforced sand material. The cohesiveness and the water-retaining property of concrete produced by using the machine-made sand are improved through the main functional raw materials, and the fluidity of the concrete produced by using the machine-made sand is reduced through the additional functional raw materials. Therefore, the machine-made sand can improve the cohesiveness and the water-retaining property while reducing the flowability of concrete, so that the strength of the produced concrete is greatly improved.
本发明涉及预拌混凝土用材料技术领域，公开了一种用于预拌混凝土的机制砂，包括普通砂料、加强砂料以及添加料，所述普通砂料由砂岩、石英砂岩、矿渣和尾矿组成，所述加强砂料由花岗岩、玄武岩、流纹岩和石灰石组成，所述添加料由主要功能原料和附加功能原料组成，本发明通过在常见的普通砂料、加强砂料中添加了由主要功能原料和附加功能原料组成的添加料，通过主功能原料使得使用本发明机制砂生产出来的混凝土的粘聚性和保水性得到了提高了，通过附加功能原料使得使用本发明机制砂生产出来的混凝土的流动性得到了降低，进而使得本发明的机制砂在降低混凝土流动性的同时还能提高粘聚性和保水性，从而大大提高了生产出来的混凝土的强度。
