I. Product Introduction
This series of grinding aids primarily consists of organic surfactants and alkanolamines, with other alcohols as supplementary ingredients in a liquid form. It is typically brownish and transparent, has no irritant odor, and does not harm human health or the performance of cement concrete.
Specs: 250 kg/bag, 1 ton/bag, loose bulk available in three sizes
Density: (20℃±1℃) 1.15-1.25 (g/cm³)
pH Value: (20℃ ± 1℃) 8-10
Solids Content: 50～70 (%)
Product shelf life: 12 months; the use of the product in cement does not affect the cement's shelf life.
Recommended Dosage: 0.02—0.05% (m/m) of cement by weight
Section II: Applicability and Effectiveness
This series is primarily suitable for silicate cement, ordinary silicate cement, blended silicate cement, slag silicate cement, fly ash silicate cement, masonry cement, and pozzolanic silicate cement.
Products are categorized by function into early-strength, delayed-strength, yield-enhancing, and comprehensive types, among others.
Early-strength products, used in the cement production process, can increase the compressive strength of cement by over 4.0MPa in 3 days, under the condition that the cement proportion and fineness control indicators are basically consistent, and the increase in the standard consistency water requirement of cement is less than 0.5%.
High-performance product for cement production, capable of enhancing the compressive strength of cement by over 8.0MPa after 28 days, while maintaining a standard consistency water demand increase of less than 0.5%.
High-yield products for tube mill cement production, capable of increasing the cement grinding output by over 15% under conditions where cement proportioning and fineness control indicators are basically consistent.
Comprehensive product for the cement process, which can reduce the cement clinker consumption by over 6% while maintaining consistent cement proportion and fineness control indicators, simultaneously increasing the admixture content by the same percentage and boosting output by over 8%.
Section 3: Usage Examples
IV. Characteristics of Cement Using This Aid-Milling Agent
The fluidity of cement powder will increase.
2. Slight increase in cement paste fluidity.
3. Standard consistency water content slightly altered (when the types of admixture are the same);
4. Setting time slightly reduced.
5. The cement's 45μm sieve residue will decrease, but the specific surface area value will not increase. Use the 45μm sieve residue to control the fineness of the ground cement.
V. Storage Methods and Conditions
This series of grinding aids is a weakly alkaline liquid. It is recommended to store in plastic storage containers with a sealed storage environment. The storage equipment should be equipped with a circulation system, and the product should be circulated regularly to maintain uniformity. The recommended storage temperature is -10℃ to 40℃.
Section 6: Method of Addition During Use
When there's no need to increase the dosage level, the metering pump can be directly used for measurement and addition.
When increasing the feed height of the grinding aid, it is generally added using a two-stage pumping method. The illustration is as follows:
Companies using our aid-milling agent provide our customers with storage tanks, related measuring equipment, and methods for detection and control of feed rate.
Section 7: Cautionary Notes
1. This abrasive aid should be used after passing inspection. Acceptance inspection methods include:
The simplest method is to compare the density, pH value, color, or solid content of the newly arrived grinding aid and the sample of the grinding aid that has been used and proven to be qualified, under the same temperature conditions. If both are within the error range, they can be considered qualified for use.
(2) Utilize a cement without additives that has the same composition as cement production. In the same laboratory, conduct a cement strength blending test using a retained sample of the grinding aid JT-IICS, which has been confirmed as qualified through usage, and a new batch of grinding aid sample. The blend is considered acceptable if the three-day strength of both is within the error range. Generally, a single method is used when continuously applying the grinding aid, while two methods are employed only when there is significant disagreement regarding the quality of the grinding aid.
2. When handling and storing barrel-assisted grinding agents, prevent dropping, crushing, external pressure, and exposure to high temperatures. The stacking height should not exceed two barrels.
Before use, please check the company logo on the package, then open the lid. Confirm the product and model are correct before use.
4. This product has slight corrosive properties to the skin. In case of contact, rinse with clean water immediately, and do not ingest or consume.
5. When using this product, if the ambient temperature remains below -5℃ for consecutive 5 days, it is advisable to take insulation measures to prevent increased viscosity from affecting normal use.
6. Shelf life of this product: 12 months.
