随着城市建设的发展和施工技术的进步,人们对混凝土的品质指标和经济指标提出了更高的要求,从而促进混凝土向高强、轻质、流态和耐久性方面发展。将逐步压缩和减少普通混凝土的用量,着重发展型(或绿色)高性能混凝土。
With the development of urban construction and the progress of construction technology, people put forward higher requirements for the quality index and economic index of concrete, so as to promote the development of concrete to high strength, light weight, flow pattern and durability. The state will gradually compress and reduce the amount of ordinary concrete, and focus on the development of environment-friendly (or green) high-performance concrete.
搅拌是混凝土生产工艺过程中很重要的一道工序,因为混凝土配合比的设计是按细骨料恰好填满骨料的间隙(见图1),而水泥胶质均匀地分布在粗细骨料的表面,只有将配合料搅拌得均匀才能得到密实的高质量混凝土。同时,通过搅拌可塑化、强化混凝土,所以混凝土搅拌机是混凝土生产的核心装置之一,用于完成混凝土的均匀拌和,保证其宏观均质性和微观均质性。
Mixing is a very important process in the concrete production process, because the design of concrete mix proportion is to fill the gap of aggregate exactly according to the fine aggregate (see Figure 1), and the cement colloid is evenly distributed on the surface of coarse and fine aggregate. Dense high-quality concrete can be obtained only by mixing the mix evenly. At the same time, the concrete can be plasticized and strengthened by mixing, so the concrete mixer is one of the core devices of concrete production, which is used to complete the uniform mixing of concrete and ensure its macro homogeneity and micro homogeneity.
混凝土搅拌的目的是使混凝土中的各组分混合成一种各物料颗粒相互分散、均匀分布的混合物。搅拌好的混凝土是否质地均匀,可通过从混凝土中随机抽取一定数量的试样进行分析来评定,如果各试样的配合比基本相同,便可认为该混凝土已混合均匀了。
The purpose of concrete mixing is to mix the components in the concrete into a mixture in which the material particles are dispersed and evenly distributed. Whether the mixed concrete has uniform texture can be evaluated by randomly selecting a certain number of samples from the concrete for analysis. If the mix proportion of each sample is basically the same, it can be considered that the concrete has been mixed evenly.

Thickened King Kong bridge, stable vehicle body load during full load operation, and safety production is the key. Four wheel drive, the whole vehicle has full driving power and worry free operation.
他可以灵活的在农村进行施工,做混凝运输工作,利用车身小巧,行驶灵活的优点可以在隧道、院落、高铁等狭小的地方进行混凝土施工。像我国一些多以山区为主的地区,很多道路崎岖狭窄,可能一般的搅拌车连5米的村门口都无法开到,而4方的自上料搅拌车,整车宽度只有2.6米,通过性上佳,狭窄的农村道路一样可以轻松通过。另外他占地小,三位一体,省时省力,机动灵活,很适合农村建设用。
He can flexibly carry out construction in rural areas and do concrete transportation. Taking advantage of small body and flexible driving, he can carry out concrete construction in narrow places such as tunnels, courtyards and high-speed railways. For example, in some mountainous areas in China, many roads are rugged and narrow. It is possible that the general mixer truck can not even drive to the village gate of 5 meters, while the 4-party self loading mixer truck is only 2.6 meters wide and has good trafficability. It can easily pass through narrow rural roads. In addition, it covers a small area, Trinity, time-saving, labor-saving, flexible, and is very suitable for rural construction.
