自上料搅拌车。混凝土是指由胶凝材料将集料胶结成整体的工程复合材料的统称。通常讲的是混凝土是指用水泥做胶凝材料,砂、石做集料,与水按一定比例配合,经搅拌而得的水泥混凝土,它广泛用于土木工程。搅拌车一般是按方量来分的,方量指的是罐体的容积,并不是混凝土的重量,不同的混凝土装在搅拌罐内,质量也是不同的,这是因为不同的混凝土密度是不同的,混凝土按照表观密度的大小可分为:重混凝土、普通混凝土、轻质混凝土三种。
Self feeding mixer. Concrete refers to the aggregate cemented by cementitious materials into a whole engineering composite materials collectively. Generally speaking, concrete refers to the cement concrete mixed with cement as cementing material, sand and stone as aggregate and water in a certain proportion. It is widely used in civil engineering. The mixer truck is generally divided according to the volume, which refers to the volume of the tank, not the weight of the concrete. Different concrete is installed in the mixing tank, and the quality is different, because different concrete densities are different. According to the apparent density, concrete can be divided into three types: heavy concrete, ordinary concrete and light concrete.

Self feeding mixer. The apparent density of heavy concrete is more than 2500kg / m3, which is made of very dense and heavy aggregate, such as barite concrete, steel chip concrete, etc. they are impervious to X-rays and gamma rays. In the process of transportation of such high-density concrete, the driver should pay great attention to it. Because of its high density, the mixer truck with the same volume is transporting heavy concrete The total mass will increase a lot, the inertia of the vehicle will increase a lot, so in the process of driving the vehicle, the speed should not be too fast, the brake should not be too fast, especially when turning, we must slow down the speed and drive carefully; and because of its high density, it is not easy to mix, which is also a test for the reducer of the mixer.

自上料搅拌车。普通混凝土就是我们在建筑中常用的混凝土,它的表观密度在1950-2500Kg/m3之间,集料为砂、石等等,这种混凝土是搅拌车常运输的一种,在装料,卸料按照规定来做就行,运输时间一定不要超过混凝土凝结的时间。
Self feeding mixer. Ordinary concrete is commonly used in construction. Its apparent density is between 1950-2500kg / m3, and the aggregate is sand, stone and so on. This kind of concrete is often transported by mixer truck. When loading and unloading, it should be done according to the regulations. The transportation time must not exceed the setting time of concrete.
自上料搅拌车。轻质混凝土是表观密度小于1950Kg/m3的混凝土,它又可以分为轻集料混凝土,多孔混凝土,大孔混凝土。这些混凝土的密度相对较小,装运在搅拌罐内,整车的质量相对较轻,驾驶员在驾驶过程中也就相对比较轻松。
Self feeding mixer. Lightweight concrete is the concrete with apparent density less than 1950kg / m3. It can be divided into lightweight aggregate concrete, porous concrete and macroporous concrete. The density of these concrete is relatively small. When they are transported in the mixing tank, the weight of the whole vehicle is relatively light, and the driver is relatively easy to drive.
