sodium lignosulfonate superplasticizer are surfactants. After they are added to concrete, the hydrophobic groups are directionally adsorbed on the surface of cement particles, so that the cement has a negative charge. The cement particles with the same charge are mutually repulsed and dispersed under the action of charge repulsion. The flocculent structure formed by the cement at the initial stage of adding water becomes a dispersed structure, and the free water in the flocculent condensate is released, so as to achieve the purpose of water reducing agent.
Therefore, adding wood calcium superplasticizer into concrete can reduce the water consumption of concrete mixture, reduce water cement ratio, improve workability, facilitate pumping and improve the strength, compactness and durability of concrete
It is a high range water reducer, high concentration naphthalene-based superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate SNF, PNS and FDN etc. Na2SO4 has 3 grades:5% 10% 18% for exporting markets,in domestic we also have 3% 23% Na2SO4 content FDN.It contains no chloride, non-corrosive to steel bars, non-poisonous, odorless, and non-flammable.
Sprayed concrete is a fast hardening material for stabilization and support of structures and for concrete applications without using any moulds. Sprayed concrete is an interaction of man, machine and concrete. Man, personified in the work of the nozzleman, requires technical skills and dedication to the job. The operator must be able to rely fully on the machine and the sprayed concrete material. It is the interaction and quality of these components that finally determines the success of the sprayed concrete application Sprayed Concrete has many advantages Application to any elevations because sprayed concrete adheres immediately and bears its own weight Can be applied on uneven substrates Good adhesion to the substrate Totally flexible configuration of the layer thickness on site Concreting without formwork Reinforced sprayed concrete is also possible (mesh/fiber reinforcement) Rapid load-bearing skin can be achieved without forms or long waiting times. Sprayed Concrete Applications: - Excavation stabilization in tunnneling and mining construction - Slope and trenching stabilization - Protective lining - Concrete repair (concrete replacement and strengthening) - Special lightweight load-bearing structures - Restoration of historic buildings (stone structures) - Sealing works - Construction of swimming pools User Notes: The technical details and recommendations contained in this data sheet are given in good faith and represent the best of our knowledge and experience at time of priting.

Uses SM-P is recommended strongly for use in all ready-mix, precast, and prestress concrete applications where low water-cement ratio, low permeability, high durability, high strength concrete is specified or high slump flowable concrete is required. SM-P can be applied in various concrete, including high strength concrete, high fluidity concrete, high duration concrete, aluminate cement refractory concrete, grouting material, steam curing concrete, high strength mortar, gypsum products, and so on. Advantages Increase concrete early strength. Promote workability. Increase flowability. Increase cohesiveness and segregation resistance. Shorten mold take-off time. Keep water/cement to a minimum. Promote air stability. Compatible with cements, gypsums and other admixtures. Reduce bleeding at high slumps. Woven fabric bag with plastic liner. Net weight: 20kg +/- 0.13 kg It is easy to absorb moisture from air. So it must be kept in original sealed bag and stored at dry condition. The shelf life is one year. This product is non-toxic and non-flammable. So there is no special transportation requirement.
Chuangbangfª super performance mortar admixture is a new type super concentrated building mortar admixture , it is a macromolecule polymer which mix and mixing with many kinds of natural materials, it can upgrade the physical performance of the mortar .It is easy to mix , it can diffuse the cement, make the cement and grout distributed evenly, to reach the effect of no precipitation and no sweating from mud , can substitute lime , loess lotion , fly ash and some other mortar admixture . 25kg/bag
Fly ash are produced principally at coal-fueled electric power plants , which is one of the residues generated in the combustion of coal. Owing to its pozzolanic properties, fly ash is used as a replacement for some of the portland cement content of concrete. It can improve concrete performance, making it stronger, more durable, and more resistant to chemical attack. The reuse of fly ash also creates significant benefits for our environment.

The Ground Granulated Blast Furnace Slag (GGBS/GGBFS) is a type of eco-friendly green building material and high quality secondary cementitious material for concrete and cement. It is recognized as one of the best secondary cementations material for building high durable concrete stricture in the world today! GGBS has taken over a top place of high-performance cement and concrete mineral additives with its unique characteristics of hydration, low-price raw material. GGBS is obtained by quenching molten iron blast furnace slag (a by-product of iron and steel making) in water or steam. It is then further grounded into the desired fineness in terms of the required particle size distribution. The main components of blast furnace slag are CaO (30-50%), SiO2 (28-38%), Al2O3 (8-24%), and MgO (1-18%). The other important aspect of GGBS is its superiority in concrete durability which extends the lifespan of buildings from fifty years to a hundred years.
