Concrete additive anti-segregation agent increases viscosity, water retention and improves fluidity

Working principle and structural characteristics
Concrete mixer truck (hereinafter referred to as the mixer truck) consists of two major assemblies: the chassis and the upper part composition. The upper part consists of the mixing drum, sub-frame, feeding and discharging device, control system, hydraulic system, electrical system, water supply system and guardrail. The specific structure is shown in the figure below:
(1) Working principle
The built-in blades are used to continuously forcefully stir the concrete so that it does not produce any gas within a certain period of time (up to 90 minutes). Solidification phenomenon, so that the mixer truck can still meet the usage requirements after arriving at the construction site.
(2) Structural features
1. Mixing drum
The mixing drum is a key component of the entire mixing truck. As a container for storing concrete, it plays a decisive role in preventing it from solidifying and segregating. It consists of a mixing drum, a supporting wheel, etc.
The cylinder body is welded by a front cone section, a rear cone section, a cylindrical section, a head, a blade, a feed cone, a raceway, etc. The front end is connected with the reducer, and the rear end is supported on the subframe through supporting wheels. The supporting wheel plays the role of supporting the drum body and is composed of a support, a bearing seat, a shaft, a bearing, etc.
The mixing cylinder is made of high-strength steel plate and the blades are made of high-strength fine-grained alloy steel (its wear resistance is 1.6 times that of Q345), which has higher wear resistance. The whole head is formed by spinning at one time and has sufficient rigidity and strength after welding with the reinforcing plate.
The small feeding cone directly affects the feeding speed of the entire vehicle. If the speed is too fast, segregation will occur, and if the feeding speed is too slow, it will affect work efficiency. Therefore, the feeding cone is designed in a funnel shape with a large diameter, and the feeding speed is maintained at 3.2m3/min, which can ensure smooth feeding and prevent concrete from overflowing.
The raceway is a forged piece and is forged as a whole. After the entire cylinder is welded, the outer ring is processed to ensure coaxiality requirements.
The optimized design of the mixing drum has reliable structural rigidity, good wear resistance, smooth incoming and outgoing materials, and extremely low residual content. It can mix concrete and transport ready-mixed concrete without any leakage. The phenomenon of material segregation ensures the homogeneous performance of concrete.
2. Sub-frame
The sub-frame of the mixer truck is the main load-bearing part. Almost all the loads during operation are supported by it. In addition, the bumps, acceleration and deceleration of the road surface during driving can cause damage to the vehicle. The impact load places high demands on the structure of the subframe.
The entire subframe consists of the main beam, front support frame, and backstage support frame.
The main beam adopts an overall box-shaped structural beam, which fundamentally enhances its torsion resistance, bending resistance, and tensile resistance and ensures the rigidity requirements. An auxiliary beam is installed between the two main beams to adjust the main beam. The stiffness of each section allows the load to be more evenly distributed over the entire length of the subframe.
It is inevitable to encounter special circumstances during driving and require emergency braking. The inertia force caused by this is very large. In addition, the mixing drum itself has a certain inclination angle, so the front platform of the subframe must The load is relatively much larger, and this part of the load is mainly added to the six bolts connecting the reducer and the front support base. In order to prevent the bolts from being sheared and causing an accident, a thrust stop is installed on the front support base. block so that the bolts are not affected by shear force and ensure the safety of the vehicle during operation.
Grouting mortar is generally special mortar, and dry mortar includes special mortar and ordinary mortar.
Grouting mortars are divided into: grouting materials, self-leveling materials, grouting materials, etc. The distinctive features are fluidity and self-healing. There are many types of dry mortar, such as: grouting agent, adhesive, putty, Insulation mortar, etc.

Mortar: The binding material used for bricklaying in buildings. It is made of a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.) mixed with water. It is also called mortar or mortar.

Mortar is made of cementitious materials (cement, lime, clay, etc.) and fine aggregate (sand) mixed with water. Commonly used ones include cement mortar, mixed mortar (or cement-lime mortar), lime mortar and clay mortar.
