We all know that cement is a building material. Due to its superior performance and economy, there are countless finished buildings made of concrete and it is widely used in the field of modern bridge construction. However, because it is a porous material, this porosity allows external corrosion factors to easily invade its interior, causing damage to the concrete structure. Therefore, many manufacturers will choose admixtures to improve the quality of concrete when synthesizing. What are the concrete plastic retainers with better effects? What indicators should be referred to?
In the daily operation of bridges, due to Diseases such as carbonization, freeze-thaw, chloride ion erosion, and alkali-aggregate reaction have severely reduced the durability of bridges. In order to reduce or even avoid bridges from being affected by cement-related durability diseases, many viaducts and bridges in China have coated columns and other substructures with a coating. Highly penetrating cement concrete protective agent.
Based on the performance indicators of concrete plastic retaining agent and user requirements, it complies with national, industry or enterprise standards. Admixtures in water can be decomposed into anions and cations. According to the principle of same-sex charge repulsion and opposite-sex attraction, plastic retaining agent manufacturer, admixtures can change the distribution of pores in the mortar, making the pore size smaller, thereby improving the compression resistance and resistance of the mortar. Shear strength
Plastic retaining agent product performance
1. This product is suitable for applications with poor aggregate gradation, low cementing material dosage, and poor flow properties.
2. This product can adjust the workability of concrete.
3. This product can reduce the slump loss over time.
4. This product has a certain auxiliary water-reducing effect and is suitable for various types of water-reducing mother liquors.
Main technical characteristics of plastic retaining agent
1. It can effectively inhibit the hydration reaction speed in the initial and induction stages of cement hydration, and extend the setting time and plastic retention period of cement.
2. It can effectively control the loss over time of ready-mixed commercial concrete mixed with pumping agent and high-efficiency water-reducing agent, slump and fluidity, so as to maintain good reliability within the required time. Pumpability and construction performance.
3. The initial setting time of concrete mixed with plasticizer can be extended as needed, but the interval between initial setting and final setting is short, which overcomes the problem that general retarder makes the final setting time too long and causes early strength development. The disadvantage of being too slow.
4. The plastic retaining agent improves the later strength and comprehensively improves the physical and mechanical properties.
5. The plastic retaining agent has a certain water-reducing effect, and the high-efficiency water-reducing agent can be used in combination with it to reduce the dosage and cost.
The selection of concrete plastic retainers with better effects mainly refers to the above indicators. I hope that there should be some reference when choosing now. </p
