nihil molestiae consequatur

Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

Chemical Admixtures for Concrete Cellulose Ether

2019-3-23  The mechanism of retardation is again based on adsorbtion of retarding admixture on the surface of the cement particles. The large admixture anions and molecules that are adsorbed on the particles hinder further reaction between cement and water, that is, they retard setting. They slow down the rate of early hydration of C3S.

Waterproofing admixtures prevent water from penetrating concrete in its hardened form after application. These admixtures reduce porosity, thus preventing water from seeping in and diluting the specified strength of the concrete for a particular role. Waterproofers play a key role in helping concrete maintain its strength over the long haul.
