The difference between self-loading concrete mixer and forced concrete mixer is:
1. The mixing tank works differently:
In the self-loading concrete mixer, the mixing drum rotates at an appropriate speed; while the mixing drum of the forced mixer is fixed.
2. Different mixing uses:
Self-loading concrete mixers are mostly used to mix general plastic concrete, and mandatory mixers are mostly used to mix dry hard concrete and lightweight aggregate concrete.

When using an automatic loading mixer truck to load concrete, the rotation speed of the mixing drum is 2-10 rpm. During transportation, ensure that the speed of the mixing tank on the horizontal road is 2-3 rpm. If the slope is greater than 50, when the road is uneven or shakes violently, stop mixing and spinning, and wait for the road to improve before mixing and spinning.

The quality of the tunnel depends on the quality of the process. The quality of the process depends on the quality of the excavation, initial support and drainage and drainage, etc. The better control of the initial support and drainage and drainage can strengthen supervision, so the focus is on the quality of the excavation, which depends on the quality of the excavation The quality of drilling and blasting means that in theory, the quality of the initial support without over-excavation

The horizontal cement tank is a new type of cement silo designed by our factory to be matched with the mobile batching plant. This cement silo adopts a slow-pressure structure, which can effectively place the cement arching phenomenon, and at the same time cooperate with a special flow-assisting device to achieve a uniform cement speed. Material is not compacted during long-term storage, hidden dust collector to ensure that there is no dust.

Concrete slump mainly refers to the plasticizing performance and pump ability of concrete. The factors that affect the concrete slump mainly include gradation change, water content, weighing deviation of the scale, and the amount of admixture, which are easily overlooked. Cement temperature, etc. Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete.

(1) When the concrete strength level is less than C50, the slump should be less than 180 mm, and when the strength level is greater than C50, the slump should be greater than 180 mm; (2) When the specified concrete slump is less than 40 mm, the allowable deviation is ±10 Mm; when the specified concrete slump is 50~90 mm, the allowable deviation is ±20 mm; when the specified concrete slump is greater than 100 mm, the allowable deviation is ±30 mm;

Concrete refers to a general term for engineering composite materials in which aggregates are cemented together by cementitious materials, and is widely used in civil engineering. Because it consists of solid phase, liquid phase, and gas phase, some bubbles will inevitably be produced after the concrete is poured. But the existence of these bubbles will not only affect the appearance of the project, but more importantly, it will have some hidden risks.

For the treatment measures of concrete bubbles, select the appropriate vibrating equipment, and determine the appropriate vibrating time, vibrating radius and frequency. At the same time, vibrate according to the method of "fast insertion, slow pumping, up and down drawing", the vibrating rod should be straight up Quickly insert and pull slowly, no leakage is allowed. When vibrating, it should twitch up and down.

When the average day and night temperature is lower than 5 ℃ or the low temperature is lower than -3 ℃, it should be treated as winter construction. When the ambient temperature is lower than 5 ℃, it is forbidden to sprinkle the concrete surface for curing. At this time, the curing liquid can be sprayed on the concrete surface, and appropriate heat preservation measures should be taken.

What is hydraulic concrete? In order to achieve the purpose of flood control, irrigation, power generation, water supply, shipping, etc., it is usually necessary to build different types of buildings for water blocking, flood discharge, water delivery, sand discharge, etc. These buildings are called hydraulic structures.

From the long winter twelfth lunar month to decisively press the "pause button" for the prevention and control of the spread of the new crown epidemic, to the early spring of February to grasp the epidemic prevention and control and the economic development and start the "fast forward button" to resume production in time, concrete and cement All enterprises and employees in the product industry have experienced this difficult and unforgettable process.

High-tech projects are the focus of local governments to support resumption of work. Since February, more than 50 production bases of Jianhua Building Materials Group have resumed production and resumed production. On the premise of doing a good job in epidemic prevention and control, each subsidiary accelerated production and guaranteed transportation, helped the major projects in various regions to resume work smoothly, and recaptured the delayed construction period .

At present, concrete pumps have been widely used in the construction of concrete projects. By adopting the concrete delivery method, the construction party can not only reduce costs, but also save construction time and standardize the construction site. However, some problems will inevitably occur during the use process, such as the flow interruption during the pumping process, so why does the concrete delivery pump have a flow interruption? What harm will it cause?

According to the various data provided by the concrete mixing station, I summarized some experiences and lessons in the application of pumping commercial concrete to block pumps and pipes, and hope to help you concrete friends. The characteristics of pumped concrete are uniform material quality, stable quality, and fast feed speed. It can continuously complete vertical and horizontal transportation at one time, with high production efficiency and labor saving. Because the concrete delivery pump

Machine-made sandstone powder (referred to as powder below 75μm), reaching 3312%.

The unsuitable performance is firstly that the slump of fresh concrete is small and the expansion is small, but the amount of water reducing agent is already quite large at this time. The popular saying is "unopenable"; secondly, the slump loss is large, Sometimes there is even false setting, that is, the cement slurry is very thin at the beginning of the mixing, but it quickly sticks and dries, and the workability of the concrete after the machine is very poor;

The third step of the adaptability test is to find out the saturation blending value of the superplasticizer used for this cement. If two or more superplasticizers are mixed, the cement paste is passed through the total amount of the mixture. Test to find the saturation dosage point. The closer the amount of superplasticizer is to the saturated content of the cement, the easier it is to obtain good adaptability.
