In the cement industry where huge amounts of clinker are dry-ground, a large number of studies have been carried out on the grinding aids to improve grinding efficiency of the cement clinker; beneficial observations have been obtained for several decades (Iwabuchi, T. and Res. Assoc, J., 1970).
into the mill at low dosage (0.01-0.05%) during cement particle grinding process. CGA improves the efficiency of this grinding process, reduces particle size, and reduces energy use without impairing cement performance [3]. The use of CGA in cement production process brings some benefits including the
The results indicated that grinding the PSA for 10 minutes and use it to replace up to 50% of the cement content have similar mechanical and durability performance to ordinary Portland cement ...

The use of cement has raised some questions, from various nutritionists and extension workers, about possible negative effects on animals. In fact, research on the use of cement or its by-product, cement kiln dust, as a mineral supplement have not shown such adverse effects at levels of 1 to 3 percent of the total diet dry matter.
Concrete grinding is actually a lot easier than I thought it was going to be. Obviously, this depends so much on what you are trying to do and the circumstances, but the basic operation of the machines was easier than expected. I definitely had some issues that if avoided, would have help the job go faster and the results would have been better
The influence of beet molasses on performances of blended cement was studied by comparing with one commercially available, triethanolamine-based grinding aid (TA).

aid in cement grinding process is economically and envi- ronmentallysustainable[12].Zhangetal.usedwasteglyc- erin, industrial lignin, and molasses as grinding aids for
In this paper amine acetate was synthesized using the product from acetic fermentation of molasses and it was followed by fermentation of molasses through FT-IR and pH measurement. The fermented product was neutralized with tertiary amine, and finally were adding glycols into the grinding admixture.
Recent studies which involve molasses usage as cement grinding aid have shown that energy resources can be used efficiently using less energy for grinding (Gao et al., 2011, Li et al., 2015). Molasses are specifically preferred by cement factories for their economical and logistics benefits.
The present invention involves the use of Spent Molasses Concentrates ("SMC") produced as a concentrated residue after evaporation of the raw waste water obtained from distillation of beet or cane molasses, as an extender for a polyoxyalkene polyol grinding efficiency enhancer selected from glycol, glycerol, or a mixture thereof.
Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1].
setting time was compared with and without the use of Molasses. The effect of Molasses on these properties of cement was compared with the effect of sugar on these properties of cement. The water-reducing effect in different mixes of cement-sand mortar (1:3, 1:4 and 1:5) has been
Blackstrap molasses is used primarily as an animal feed additive but also is used to produce ethanol, compressed yeast, citric acid, and rum. Edible molasses syrups are often blends with maple syrup, invert sugars, or corn syrup. Sugarcane is produced and harvested for two purposes: production of cane sugar and use as seed for subsequent plantings.

The subject desugared molasses may act as a grinding aid or performance enhancer in the manufacture of cementitious materials. Desugared molasses is typically available as a liquid material, but it may be dried for use according to the present compositions and method.
Cane molasses improves the cement clinker grindability. • Cane molasses affects cement setting time and microstructure. • Proper cane molasses increases the cement compressive strength. • It has notable impact on the cement compatibility. • It is logistical and economically feasible, also environmentally friendly. Abstract

During the concrete grinding process, concrete floor grinders tend to create a huge amount of dust. This makes the use of dust-control equipment mandatory to keep concrete dust from going airborne. In this case, a dust vacuum collector will come in handy.
The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it is to burn.
Meanwhile, it is an urgent concern to find a cheap alternative to the present Portland cement grinding aids. However, the available literature has several limitations in properly evaluating the feasibility of using cane molasses as a Portland cement grinding aid.
Li et al. used waste oil as grinding aid during cement grinding process. As a result, it was suggested that the use of waste oil as grinding aid in cement grinding process is economically and environmentally sustainable . Zhang et al. used waste glycerin, industrial lignin, and molasses as grinding aids for composite cements.
The biggest disadvantages of using an angle grinder for concrete grinding are: 1. Size. As angle grinders commonly use blades up to five or seven inches in diameter, it would take a long time to level a concrete floor using this tool. If you are working on a floor, a floor grinder would be a better option. 2.
The modified molasses can also be used together with further substances, in particular with cement additives or concrete admixtures, such as, for example, grinding aids, antis, colorants, preservatives, air-entraining agents, shrinkage reducing admixtures, further liquefiers and/or corrosion inhibitors.
After the analysis of the grinding efficiency and physical performance of the blended cement with single grinding aids, the physical performance of the blended cement with composite grinding aids containing waste glycerin, industry lignin and cane molasses were researched, the results are shown in Table 6, the weight ratio of each grinding aids ...
Recent studies which involve molasses usage as cement grinding aid have shown that energy resources can be used efficiently using less energy for grinding ( Gao et al., 2011, Li et al., 2015 ). Molasses are specifically preferred by cement factories for their economical and logistics benefits.
Molasses is generally used as a grinding aid in cement and as a water reducer and retarder in concrete. In China, the output primarily consists of sugarcane molasses. In this paper, the effects of sugarcane molasses on the physical performance and hydration chemistry of conventional Portland cement were investigated. The setting times, the normal consistency …
