Problems solved by technology

[0003] But for all-light concrete, there is a big contradiction between its thermal insulation performance and its own strength. Since the strength depends on the density of all-light concrete, the greater the density and the greater the self-weight, the greater the strength will be. But when When the density is higher, the thermal conductivity will also be greater, so that the insulation effect of all-light concrete cannot be guaranteed. Under such problems, most all-light concrete will have low strength and cannot be effectively used in building structures that require strong support. Inside, there is room for further improvement

Embodiment 1

[0032] A kind of LC all-light concrete disclosed in this application includes light soil ceramsite, fine sand, cement, water reducer, mineral admixture and water, and the light soil ceramsite adopts honeycomb type light soil ceramsite; the mineral admixture is Including fly ash, mineral powder and silica fume, the specific weight parts of each component are shown in Table 1.

[0033] In addition, the light soil ceramsite used adopts continuous gradation, and the particle size of the light soil ceramsite is 5-10mm. The water reducing agent used has a solid content of 20%, and its water reducing rate is greater than 30%.

[0034] The preparation method of this kind LC all-light concrete comprises the following steps:

[0035] S1: Put cement, mineral admixture, light soil ceramsite, water, and water reducing agent into the concrete mixer for mixing to obtain primary mixed materials;

[0036] S2: Put the light soil ceramsite into the primary mixture obtained in S1 and stir to ob...

Embodiment 2-6

[0041] The difference from Example 1 is that the parts by weight of each component included are different, and the detailed values ​​are shown in Table 1.

Embodiment 7

[0043] The difference from Example 3 is that the light soil ceramsite used in this example is a conventional light soil ceramsite that is not a honeycomb type light soil ceramsite.

Abstract

The invention discloses LC full-light concrete and a preparation method thereof and belongs to the field of concrete preparation. According to the technical scheme key points, the LC full-light concrete is prepared from the following components in parts by weight: 900-1160 parts of light-earth ceramsite; 600-780 parts of fine sand; 310-380 parts of cement; 8.5-10.2 parts of a water reducing agent;230-285 parts of a mineral admixture; and 135-165 parts of water. According to the scheme, when the light-earth ceramsite is selected as the concrete aggregate, the compressive strength of the finally prepared LC full-light concrete can be effectively improved. Due to the fact that the light-earth ceramsite is rougher, the light-earth ceramsite has larger surface area and stronger water absorption capacity, the bonding capacity is stronger when the light-earth ceramsite is combined with cementing materials such as cement, and the light-earth ceramsite distributed in the coarse aggregate is stably connected with other light-earth ceramsite around the light-earth ceramsite. Finally, the compressive strength of the concrete formed by the coarse aggregate is improved, so that the LC full-light concrete can be used for carrying out compressive load-bearing on large vehicles when a main road of a road is paved.

Description

technical field [0001] The present application relates to the technical field of concrete preparation, in particular to a kind of LC all-light concrete. Background technique [0002] LC full-light concrete, also known as lightweight aggregate concrete, is a concrete prepared by using lightweight coarse aggregate and lightweight fine aggregate. It is widely used in industrial and civil buildings and other projects, which can reduce the weight of the structure; Excellent seismic performance; save material consumption; improve component transportation and hoisting efficiency; reduce foundation load and improve building functions (insulation and fire resistance, etc.) and other benefits. [0003] But for all-light concrete, there is a big contradiction between its thermal insulation performance and its own strength. Since the strength depends on the density of all-light concrete, the greater the density and the greater the self-weight, the greater the strength will be. But when ...
