PDX-VM: Additives for cement vertical mill
DESCRIPTION
- Vertical mill is a technology well known for its efficiency in grinding clinkers, raw materials, slag, etc.
- The grinding process in a vertical mill requires the use of water (up to 3%) to decrease the vibration. The addition of water may cause pre-hydration, leading to the negative impacts on setting time, compressive strength and workability of the concrete.
- Prodexim has developed new formulations of PDX-VM additives specifically for vertical mills, with lower water use and less vibration.
- PDX-VM is a high-performance chloride-free formulation suitable for grinding all types of Portland or blended cements.
- The basic formulation of the PDX-VM can be customized to meet a wide range of specific requirements from our customers.
BENEFITS
- Improve productivity and grinding efficiency with less vibration, extend equipment lifetime and contribute to energy savings. The increase in the plant's production rate can exceed 10%.
- Increase cement quality (cement fluidity, pack-set).
- Promote the dispersion of cement particles in water, improve the cement / water contact, enhance cement hydration.
- Improve the setting time and the mechanical properties of concrete with no detrimental effect on air entrainment.
PDX-RF : Grinding aids for cement raw materials
DESCRIPTION
- Chemical additives used in the grinding of raw materials in order to optimize the size and homogenization of raw feed.
- The basic formulation of the PDX-RF can be customized to meet a wide range of specific requirements from our customers.
BENEFITS
- Improve fluidity and particle size distribution (PSD).

PDX-Silica fume: Supplementary Cementitious Materials (SCMs)
Description
A very fine and very reactive pozzolanic material produced from the manufacture of elemental silicon or ferrosilicon alloys. Silica fume reacts chemically with the free lime in the cement paste to form calcium silicate hydrate (CSH) gel. This reaction is called a pozzolanic reaction where the CSH gel acts as a binder to hold the constituents together and fills the air void structures in the concrete.
BENEFITS
- Reduce permeability by filling voids and capillaries.
- Increase significantly the durability and strength of concrete (compressive and flexural strength).
- Increase resistance to sulphate and chloride attacks, to alkali-aggregate reactions and to corrosion generated by de-icing salts.
- Improve the cohesion and workability of concrete.
- Standards: CSA A3001-13 Cementitious Materials Used in Concrete
