Ultrafine Grinding of Limestone with Sodium Polyacrylates as . Apr 7, 2014 Their impact on fine and ultrafine grinding of limestone was studied. Sodium polyacrylate with a low polydispersity index was found to be the most effective grinding aid for limestone and consequently applied for further nano-grinding experiments.
Similar findings were reported in the presence of sodium alginate and sodium polyacrylate . Other polymers, such as polyphosphazene might be used as well [490,491,492]. Other examples of polymer/CaPO 4 self-setting formulations might be found elsewhere [493,494]. Metallic wires might be used as reinforcements as well .
All cement pastes were prepared with a fixed water to cement ratio (W/C) of 0.29 and the dosage of the PCE in cement pastes was varied in a range of 0.2–2.0% by weight of cement (bwoc). Cement paste samples were prepared in accordance with the Chinese standard GB/T8077-2012 (2012). The detailed procedures can be found in literature . Fluidity

cement chemistry clinker cement clinker and cement faster than ordinary portland cement. it is manufactured by grinding the clinker and gypsum finer in the cement mill. good clinker quality is needed and the addition of gypsum is a little higher to maintain setting time and increase strength development. sulfate resistant cement is used where a higher resistance is required
Another two patents in 1976 and 1977 succeeded to reduce the cement content less than 3% by using dispersants such as sodium tripolyphosphate in amounts (0.01–0.05 wt.%) and fine matrix, . They replaced part of the cement with sub-micrometer particles ranging from 0.1 to 0.01 μm which could easily be dispersed without forming a gel or a sol.
The results of this study revealed that the highest grinding efficiency, without adding grinding aid, can be obtained by controlling the grinding concentration at 50%. Sodium polyacrylate showed bettter grinding effect, and the grinding rate can be increased by 10 percentage points with adding 0.6% of sodium polyacrylate. Read More
The cement industry is particularly reliant upon particle size reduction. Raw materials crushing and grinding seeks to reduce materials from roughly one meter cubes of blasted stone to a size where at least 80 percent of the raw material is less than 75 microns. Finish grinding of clinker and other cement
Lignin is an excellent raw material for the preparation of chemicals because of its rich source and low price. It also contains a variety of active functional groups, including hydroxyl, methoxy, carbonyl, carboxyl, and benzene. According to research, the two main types of lignin are alkali lignin and lignosulfonate.

(2) A quadratic model for the minislump of the cement pastes mixed with Na-Mnt was developed statistically. The optimal conditions for ct-PCE dispersion performance in Na-Mnt-incorporated cement paste were a side-chain ratio ((AA + AM):APEG) of 4:9, a monomer ratio (AA:AM) of 9:8, an initiator dosage of 2.9% and a synthesis temperature of 81°C.
The optimized constituents were: sodium polyacrylate 0.13 %, xanthan gum 0.86 %, sodium alginate 0.18 % with predicted sensory scores of 90.30. The study showed that hydrocolloids could be used as ...

Table 1 shows that as the percentage of ordinary Portland cement in the composite slurry increases (from 10 to 90%), the initial fluidity changes accordingly; after first decrease, it gradually increases. When the proportion of Portland cement reaches 90%, the pumping period could reach 28 min. The initial setting time and the final setting time also tend …
