Embodiment 1
[0022] The ceramsite concrete that present embodiment makes is LC20 / 1400 grade ceramsite concrete (that is, intensity is LC20, and density is 1400 grades), and its formula is composed as follows:
[0023] P.O42.5 Ordinary Portland cement 290kg, Class II fly ash 110kg, water 210kg, furnace bottom slag 150kg, pumping agent 6kg, ceramsite 670kg, redispersible latex 1kg.
[0024] The fineness modulus of the furnace bottom slag is 2.6, the 4.75-12mm ceramsite is coarse aggregate, and the furnace bottom slag is fine aggregate.
[0025] The preparation method of the present embodiment LC20 / 1400 grade ceramsite concrete is as follows:
[0026] 1. Weigh the ceramsite with the above weight and soak it in water for 24 hours until it is saturated with water absorption, then send it to the batching bin with a forklift, and then transfer it to the mixing host.
[0027] 2. After the furnace bottom slag is measured by the measuring scale, it is transported to the middle bucket by the incline...

Abstract
The invention provides high-fluidity pumping ceramsite concrete and a preparation method thereof. A formula of the concrete comprises cement, coal ash, water, fine aggregate, limestone flour, pumping aid, ceramsites, ceramic sand, redispersable emulsion and hydroxypropyl methyl cellulose. The method comprises the following steps: reasonably selecting respective raw materials and usage thereof according to a unit weight of concrete to be prepared, soaking the ceramsites to a saturated water absorption state in advance, then mixing with other raw materials, and stirring to prepare the ceramsite concrete. By controlling the grain size of the ceramsites and a fineness modulus of the fine aggregate, the redispersable emulsion and hydroxypropyl methyl cellulose are cooperatively added to promote the cementation of the cementing materials such as the cement, the coal ash and the limestone flour with the ceramsites, and the cohesiveness and water retaining property of the concrete are increased, and the problems of easy floating, layering and separation of the ceramsites in the ceramsite concrete are effectively solved, moreover, separation and layering of the ceramsites can be effectively avoided by using the ceramsite concrete produced according to the invention, and slump loss in a material transporting and waiting process is obviously reduced.
Description
technical field [0001] The invention relates to the technical field of ceramsite concrete production, in particular to a high fluidity pumping ceramsite concrete and a preparation method thereof. Background technique [0002] With the reform of wall materials, building energy saving is becoming more and more important, and the design and application of walls are mainly sustainable development in the direction of light weight, good energy saving and thermal insulation performance, high strength, high durability, and high safety. Therefore, compared with ordinary concrete, ceramsite concrete, which has good workability, high strength and light weight, fire resistance, self-insulation, moisture-proof and sound insulation, volume stability and durable safety, has attracted more and more attention and recognition in engineering applications. Good economic and social benefits have been achieved in reducing the weight of the structure, saving the amount of materials, comprehensivel...
