- Precautions for the application of polycarboxylic acid admixtures in commercial coagulationPolycarboxylic acid is a new type of admixture, which has high water reduction rate and high adaptability, can improve the workability of concrete, and improve the workability and quality of concrete construction. Precautions for the use of polycarboxylic acid admixtures for concrete are embodied in
- Application of Triisopropanolamine in grinding aidsIn the field of cement grinding aids, the early alcohol amine compounds used in grinding aids were mainly triethanolamine. Because triisopropanolamine has better dispersibility and later strength than triethanolamine, with the development of the cement industry and intensified competition, the appliProduct & Technology January 09, 2020
- Preventive measures for peeling of concrete pavementPreventive measures for peeling of concrete pavement1.Strictly control the quality of concrete materials(1) Control of concrete mixing materialsMedium and coarse sand should be selected, and all indicators should be consistent with national standards. The use of washed sand and sea sand is strictlyProduct & Technology January 09, 2020
- Reasons for peeling of concrete pavementConcrete has many characteristics, including low price, high wear resistance and durability, and multiple sources of materials. The application of construction engineering to it is very extensive, but during the construction of concrete pavement, because of various reasons, the peeling phenomenon ofProduct & Technology January 09, 2020
- Polycarboxylic acid water reducing agent matters needing attentionThe precautions of polycarboxylic acid water reducing agent mainly include the following six points:1. There is a problem with the adaptability of cement. For some cements, the water reduction rate is low and the slump is large. Therefore, when the cement adaptability is not good, the concrete trialProduct & Technology January 09, 2020
- Multifunctional effect of triethanolamine (TEA)Triethanolamine is an important additive in water-based cutting fluids. It has multiple functions in water-based cutting fluids:1.Synthetic water-soluble lubricantAt present, most oily agents with good lubricating properties are water-insoluble. Triethanolamine has three -OH. By controlling the ratiProduct & Technology January 09, 2020
- How to choose grinding aidsCement companies generally roughly divide grinding aids into two categories, "enhancing" and "increasing production." How should I choose? It is generally thought that if you want to increase the strength, you choose the "enhanced" grinding aid, and if you want to increase production or save electriProduct & Technology January 09, 2020
- How does slag cement behave under the action of TEA and TIPAThe slag cement has the advantages of low heat of hydration, high strength at the later stage, inhibition of alkali aggregate reaction, and resistance to sulfate corrosion, and has been used in a large number of projects. When producing slag cement, the slag is less abrasive than the clinker. So how does slag cement behave under the action of TEA and TIPA?Product & Technology January 09, 2020
- Causes of some problems after using grinding aidsCement grinding aid companies, as promoters of introducing grinding aid products into cement production, guide cement enterprises to correctly understand and use cement grinding aids, and help cement enterprises correctly judge certain problems in the application process of grinding aids, which willProduct & Technology January 09, 2020
- Effect of TriethanolamineTriethanolamine is a colorless to pale yellow viscous liquid. It can react with various acids to form esters and amide salts. It can also corrode copper, aluminum and its alloys. Triethanolamine has a wide range of effects. what's the effect? What is its main use?1.
