CEMENT VIA MICRONISATION 🪨👷👷♀️♻️💚: Cemex has developed an innovative approach to decrease CO2 emissions in cement production by reducing the size of clinker particles.When combined with proprietary admixtures, this process, called micronisation allows cement to significantly reduce its clinker factor per ton of cement, thereby minimising its carbon footprint. Additionally, clinker micronisation has the added feature of maintaining the specified development strength required by the highest global cement standards.Cemex's clinker micronisation process, pioneered by their Research and Development Center in Switzerland, offers a creative alternative to traditional clinker grinding, enhancing efficiency and significantly boosting the strength of the final product. Industrial-scale production trials have validated initial R&D findings.The production of clinker, the main cement component, represents the most carbon-intensive cement manufacturing process. Adopting clinker micronisation can reduce the clinker factor in cement products by up to 50%, which would significantly accelerate progress towards the company's decarbonisation goals."We are finding new ways to boost our decarbonisation roadmap in the production of cement and concrete," said Fernando A. González, CEO of Cemex. "We remain committed to achieving our ambitious 2030 decarbonisation goals on the path to becoming a Net Zero company by 2050"💡🌎 Sergio Menendez Kevin Cage Vanessa Smithson Mark R Brown Jorge L.

This is a Jafusen cellulose factory that provides customers with customized cellulose and formula optimization.HPMC (hydroxypropyl methylcellulose) plays multiple roles in the application of self-leveling floors:1. Adjust the fluidity and self-flowing properties of concrete or cement slurry to make it easier to spread, fill and level.2. Prevent water from evaporating too quickly and extend the working time of cement slurry.3. Improve the adhesion of concrete or cement slurry.4. Improve the compactness of concrete or cement slurry, improve the permeability resistance of the floor, and make it more durable.The amount and selection of HPMC should be based on specific construction requirements, environmental conditions and materials used.Free samples and catalogs available.Please contact me if needed.#Jafusen #cellulose #factory #additive #mortar #putty #coating #paint #tileadhesive #Gypsum #HPMC #RDP #HEC #PVA #selfleveling

Proportion of hydroxypropyl methylcellulose and cementHydroxypropylmethylcellulose (HPMC) is a commonly used additive in cement-based products because of its ability to improve workability, adhesion and durability of the material. The ratio of HPMC to cement is an important factor to consider when using this additive.In general, the ratio of HPMC to cement varies according to the specific application and desired result. However, a typical range for this proportion is 0.1% to 0.5% by weight of the cement used.When HPMC is added to cement, it can improve the water-retaining performance of the material, thus prolonging the working time. This is especially useful where large surface areas need to be covered or where multiple layers of coating material are required.HPMC improves the adhesion of cement to surfaces such as tile or wood. This helps create a more durable, longer-lasting finish for the material, which is especially important in outdoor applications.HPMC also improves the flexibility of cement, making it less prone to cracking and breaking. This is especially useful in situations where materials need to withstand changes in temperature or pressure.The ratio of HPMC to cement plays an important role in the performance of cement-based materials. By understanding the benefits of HPMC and the proper proportions to use, builders and contractors can create a quality material that is strong, durable and long-lasting.RioLeeInternationalmarketingdevisionTiantaiCelluloseCo.,LtdAdd:Zhangdian,Zibo,Shandong,255000,ChinaTEL:+86-15269390293Email:rio@ihpmc.com;cellulosics@hotmail.comWebsite:www.ihpmc.com

When were superplasticizers first used in concrete?Superplasticizers were first used in concrete in the 1930s. At that time, lignosulfonate-based additives were employed to enhance the workability of concrete. However, these early additives had certain limitations and were not very effective at reducing water content or increasing concrete strength.In the 1960s, the first generation of synthetic superplasticizers was introduced. These early superplasticizers were formulated using sulfonated melamine-formaldehyde resins and sulfonated naphthalene-formaldehyde condensates. They marked a significant improvement over the lignosulfonate-based additives by enhancing workability and allowing for the reduction of water content. Nonetheless, their performance was somewhat limited at high temperatures, and they exhibited low compatibility with other additives.A breakthrough occurred in the 1980s with the introduction of the third generation of superplasticizers. These new additives were based on polycarboxylate ethers and represented a substantial leap in performance compared to their predecessors. They had the remarkable capability to significantly reduce water content while simultaneously improving workability and concrete strength. This development marked a pivotal moment in the history of superplasticizers, as it revolutionized their effectiveness and versatility in the construction industry.#constructionchemicals #concrete #Chemicals

The cheapest and the most expensive #cement!Portland cement and it's variations are the cheapest man-made materials on Earth..The price of cement depands on numerous parameters, but in general in EU the average price of average cement for big infrastructure #concrete projects are as low as 100 EUR/t. For smaller volume the price could be separated into 6 shares:electricity cost (25-30%),fuel cost (30-35%), raw materials cost and its transportation (10-25%),amortization of investment (10-20%),chemical additives (3-5%),#co2 cost (5-10%)In general the price of cement will increase greatly in the following years, also due to green agenda.So, the price of the cheapest cement is 0,1EUR/kg.On the other hand the cement could be used also for very sofistifacted purposes like medicine. My brother is a dentist and we have done a research work about cements used in dentistry. it turns out that a so called MTA cement which is used in permanent filling of the roots of a tooth is actually a Portland cement. The only difference with usuall cement is its purity and of course certification. in principle you just need pure (p.a.) raw ingredients, a furnace and a grinder. This will be done in our lab in near future.Other cements used in dentistry are gypsum, phosphate cement, polycarboxylate cement, glassionomer cement and composite cement.Price of medical Portland cement is 10.000- 50.000 EUR/kg.This is a huge difference for actually the same material, the difference is only in heavy metals presence, application, certificates and packaging))We know that price of the cement greatly varies from continent to continent, and we don't know exactly the reason for this. . maybe in some next post we could talk about this. A very interesting topic to be discussed is also infulence of CO2 fingerprint on cement price and also carbon capture during cement production.

Clearing up cement production the ReduDust way.In cement clinker production, especially in plants operating on alternative fuels, the efficient management of bypass dust is a significant challenge. This dust, rich in chlorine and alkaline compounds, has a limited use in cement mills due to its classification as hazardous waste, resulting in high disposal costs.Our patented ReduDust process transforms this bypass dust into a valuable resource. By extracting pure NaCl and KCl salts from the dust, it is possible to recover these valuable materials and purify the residual dust from unwanted components. This purified residual can then be fully recycled back into the cement production process, increasing efficiency without adding unwanted materials.How ReduDust Works:The process begins with a crucial leaching step, where the dust is mixed with water to dissolve the salt content into a brine. Following this, the crystallization process takes place, which can be tailored to specific plant needs due to its modular nature. To understand the unique characteristics of each plant's bypass dust, we offer comprehensive development services and studies conducted in our own laboratories and small-scale pilot plant to help accurately design and customize the ReduDust system for optimal performance.For more information on how ReduDust can be integrated into your operations, visit our website or contact our technical team.🔗 https://lnkd.in/gCCn8BW#processoptimization #cement #engineering #circularity #redudust #cementplant #cementindustry
