Making concrete requires a precise mix of cementitious materials, aggregates of various sizes, water, mineral additives, and specific chemical admixtures. This complex process involves determining the right proportions, mixing, compacting, and molding, finally allowing the concrete to harden into a solid stone-like structure. In actual production and construction, the concrete ratio is crucial. By accurately determining … Continue reading
Dry-mixed mortar is a new type of building material combined with cement, fine aggregate, fly ash and other mineral admixtures and water-retaining and thickening materials, which has the advantages of stable quality, variety, and ease of construction, and it replaces the traditional mortar with its excellent performance. Raw materials are the main factors affecting the … Continue reading
1 The difference between dry mortar and traditional mortar One of the significant differences between dry mortar and conventional mortar is the use of small amounts of chemical additives for modification. If one additive is added to a dry mortar, this is referred to as primary modification; if two or more additives are added, this … Continue reading
1 On the setting time of concrete Initial setting: The initial setting time is required from the cement is mixed with water until the slurry begins to lose its plasticity. Final Setting Time: This is the time required for cement, after being mixed with water, to fully lose its plasticity and start to harden and … Continue reading
In construction, starch ethers and cellulose ethers are key additives that enhance the properties of mortars. Though they have distinct characteristics, using them together can significantly improve mortar performance. What Are Starch Ethers? starch ethers is a polysaccharide polymer compound composed of glucose, with two types of molecules, straight-chained and branched, known as straight-chained starch (content … Continue reading

I.Definition and classification of cellulose ether industry Cellulose ether, a polymer compound made by chemical reaction between cellulose and etherifying agent, plays a pivotal role in many fields, such as construction, coating, and medicine, due to its unique multifunctional properties. This multifunctional compound not only has the basic properties of thickening, suspending and stabilizing, but … Continue reading
The concentration of the methylcellulose solution, whether it’s dissolved in water or organic solvents, is a crucial factor that should be determined based on the specific application and the type of product chosen. For low viscosity products (15~100mPa·s), a concentration of 10% and 15% is recommended, while high viscosity products (400 75000mPa ·s) should not exceed … Continue reading
