Correlation between synthesis and compounding technology of polycarboxylate superplasticizer The polycarboxylate superplasticizer is designed according to the mechanism of dispersing cement to design an effective molecular structure to prevent concrete slump loss without causing significant retardation, high plasticizing effect, good fluidity and cement adaptation. Sexuality, concrete reinforcement effect is remarkable, reducing concrete shrinkage, extremely low content of harmful substances and other technical performance characteristics, thus giving concrete more excellent construction workability, good strength development, excellent durability, and good comprehensive technical performance advantages. And environmental protection features, in line with the needs of modern concrete engineering. Therefore, polycarboxylate superplasticizers are becoming the preferred admixture for the preparation of high performance concrete.

Polycarboxylate Superplasticizers, also known as high range water reducers, are chemicals used as admixtures where well-dispersed particle suspension are required. These polymers are used as dispersants to avoid particle aggregation, and to improve the flow characteristics or rheology of suspensions such as in concrete applications. Their addition to concrete or mortar allows the reduction of the water to cement ratio, not affecting the workability of the mixture, and enables the production of self-consolidating concrete and high performance concrete. This effect drastically improves the performance of the hardening fresh paste. Indeed the strength of concrete increase whenever the amount of water used for the mix decreases. The new generation of this kind of admixtures is represented by polycarboxylate ether based superplasticizers (PCEs). With a relatively low dosage (0.15–0.3% by cement weight) they allow a water reduction up to 40%, due to their chemical structure which enables goo

Latest research and development progress and market development trend of China's concrete admixture industry The China Building Materials Federation Concrete Admixture Branch conducts a nationwide survey on the production of concrete admixtures every two years. The purpose is to grasp the latest developments in the industry and provide an accurate basis for formulating industry development policies. The investigation has been going on for more than ten years.

ASA super weather resistant functional film is a new type of film material that can be laminated on synthetic resin tiles, plastic steel tiles, decorative panels and other surfaces. Compared with the traditional ASA, the surface of the PVC material is covered by the co-extrusion process, and the surface of the product is uniform and free from scratches. The surface gloss is high, fine and smooth, the product color is easier to replace, the thickness is uniform, the operation is simple, the waste is less, and the product does not need to be dried, which fundamentally solves the defects in the traditional co-sending environment and reduces the production cost. ASA super weather-resistant functional film can also be covered with the adhesive material to cover the surface of the steel plate material, completely solve the corrosion problem of the steel plate, and has broad application prospects.

A new type of cement grinding aid was synthesized from triisopropanolamine, diethanolamine, acrylic acid, HPEG400 and other raw materials. The effect of grinding aid, physical and mechanical properties and hydration products on titanium slag cement was tested.

Through the combination of TIPA and molasses, the enhanced grinding aid was studied, its grinding effect and reinforcing effect were tested, and the grinding mechanism and strengthening mechanism were discussed. The results showed that TIPA combined with molasses could make the specific surface area

Diethanol monoisopropanolamine was produced in the 1990s and is a non-toxic, skin-irritating product that is less irritating to triethanolamine and environmentally friendly alkanamines. It is mainly used as a surfactant. In the fields of cement grinding aids, daily chemical products and fabric softe

The effect of the combination of TEA and TIPA on Portland cement is similar to the superposition of the effects of the two monomer grinding aids alone, and there is no change in the hydration product due to the composite, and the hydration process is not significantly changed

Granulated blast furnace slag has high potential activity, but poor grindability. At present, the technology of cement grinding aids has been workable, but there are few systematic studies on granulated blast furnace slag grinding aids. In view of this, this article mainly studied nine kinds of aids such as triisopropanolamine, triethanolamine, glycerin, ethylene glycol, ethyl acetate, diethylene glycol, anhydrite, hemihydrate gypsum, and dihydrate gypsum.
