In many concrete projects, traditional high efficiency concrete such as naphthalene series can not meet the engineering needs more and more due to the limitation of technical performance. A new generation of water reducing agent that has attracted much attention at home and abroad, polycarboxylic acid series high performance water reducing agent, because it has truly designed an effective molecular structure according to the action mechanism of dispersed cement, has a super-dispersed type, can prevent the loss of concrete slump without causing obvious retarding, and plays a high plasticizing effect under low content. Good fluidity retention, cement to adapt to a wide range of molecular structure, large degrees of freedom, synthesis technology, high performance of a large room for strengthening concrete significantly, can reduce concrete shrinkage, harmful substance content is very low technical performance characteristics, The concrete is endowed with excellent construction workability, good strength development, excellent durability, polycarboxylic acid series of high-performance water reducer has good comprehensive technical performance advantages and environmental protection characteristics, in line with the needs of modern concrete engineering. Therefore, polycarboxylic acid series high performance water reducing agent is gradually becoming the preferred admixture for the preparation of high performance concrete. It is reported that the use of polycarboxylic acid admixtures in Japan has accounted for more than 80% of the total number of high-performance admixtures, and North America and Europe have also accounted for more than 50%. In China, polycarboxylic acid superplasticizers have been successfully applied in many large water conservancy, bridge, nuclear power and railway projects in many countries, and remarkable results have been achieved.
Shanghai Hongyun's production and application technology of concrete admixtures and cement grinding aids are at the leading level in the industry. Relying on excellent product performance and excellent technical service, we have won the favor and praise of our customers China Railway Shanghai Bureau and China Railway 10th Bureau strategic cooperation unit. The company undertakes many national key construction projects, such as Zhengzhou-Jinan high-speed Railway, Yumo Railway, ZhengWan high-speed railway, Menghua high-speed Railway and ChangGan High Railway and other projects with the 10th bureau of China Railway like Ganshen high-speed railway, Yumo high-speed railway, Shanghai-Yurong-Chengdu high-speed railway, Longlong high-speed railway and so on. projects with the 24th Bureau of China Railway include Hangzhou-Wenzhou high-speed Railway, WenYu high-speed Railway, HuYuRong high-speed Railway, and HuTong Phase II High Railway, China Railway 3rd Bureau Changjiu high-speed railway, Xiongshang high-speed railway; In Shanghai, we cooperate with Shanghai Construction Engineering and China Construction 8th Bureau. In Zhejiang, we cooperate with Zhejiang Communications Construciton Group Co., Ltd , in Hubei, our company is the supplier of Hubei Communications Investment Group Co., Ltd. Successful cooperation with Yangtze River Road and Bridge and Hubei Road and Bridge in Xianjiu Expressway project, Xiaohanying, Zhangnan, Lixian Expressway project.
At the same time, polycarboxylic acid superplasticizer also has some problems:
1. The slump retention under high temperature environment is insufficient;
2. Strong temperature sensitivity, the construction of the same polycarboxylic acid superplasticizer in different seasons, the slump retention of concrete is very different;
3. With fewer functional products, it is difficult to meet the requirements of ultra-high and ultra-long distance concrete pumping, negative temperature construction, preparation of ultra-early strength concrete and high durability of concrete;
4. High viscosity, in the preparation of high blend material and low water-binder ratio concrete, the concrete viscosity is high, which is not conducive to construction;
5. Strong sensitivity to the mud content of sand and stone aggregate.
6. The adaptation to mechanical sand is also poor, and the sensitive content affects the construction
But our experts can offer a good solution and help customers cut down their cost.
