It is a non-metallic product consisting essentially of glass containing silicates and Alumino Silicates of lime. Site powered by Weebly.
These problem indicate that there is probably a critical limit for the water content below which high HRWR dosage become not only essential but also unhelpful and undesirable, and often even harmful from a durability point of view. Click here to sign up. Thus concept of strength through durability become essential. Email the author Login required. High dosage of high range water reducing agents HRWR then become a necessity, and resulting cohesive and thixotropic, sticky mixes are equally difficult to place and compact fully and efficiently.
The study presents behavior of hybrid fiber steel fibers and polypropylene fibers reinforced concrete including mineral admixture like Alccofine The processing with other select ingredients results in controlled particle size distribution PSD. International Journal of Structural and Civil Engineering.
This results in denser pore structure alfcofine ultimately higher strength gain. The results are similar even in other two methodologies. The impetus for higher and higher concrete strengths also came from demands for exceptional increases in the height of high-rise buildings and for long span bridges.
The presence of extremely fine particles decreases the permeability and improves durability. How to cite item. According to this test the cubes were initially water-cured for 28 days, and then exposed to water pressure of 5 bars for 72 hours after which the cube was divided and the depth of water penetration measured. Help Center Find new research papers in: In high performance concrete applications, Silica Fume is generally proposed as the appropriate cement extender where high strength, low permeability are the prime requirements.
Under durability water permeability and chloride penetration were measured most commonly. Secondary hydrated products formed due to pozzolanic and Cementitious hydration reaction fills the pores. We are proud distributors alccofien Alccofine Addition of Hybrid fibers and mineral admixture Alccofine increases the ductility, crack resistance strength and durability of concrete.
The average particle size of Alccofine is 4 to 5 microns; the top size d90 is only 10 microns. Article Tools Print this article. Fire response of hybrid 11203 reinforced concrete to high temperature. USES Rock injection, Pre-injection, Post-injection, Rock-stabilization and C urtain Grouting Soil injection – Stabilization, water tightening and control of ground water Soil injection of cracks in concrete structures Grouting of anchors in rock.

Thus, it reduces the penetration of chlorides in concrete and protects embedded steel from corrosion. Penetration of less than 25 mm is generally considered to be impermeable concrete. In fact concrete slump is seen to be improved, due to the dense packing of cementitious material, producing low void content. Physically the product is unique with regards to its particle size distribution.
Alcvofine are, by nature, fascinated and indeed obsessed, by high a,ccofine and very high strength concrete.
The following are the salient features of Alccofine Enhances the strength for higher and mid range grades of concrete with optimum utilisation Provides economy in higher grades of concrete Enhances durability of concrete Improves impermeability and eliminates or minimizes thermal cracking Assured quality in terms of even and consistent Particle Size Distribution Environmentally friendly and non-hazardous to health unlike Silica Fumes Immaculate supply chain, delivered around the globe.
Elevated temperatures effects on HSC. Part 8-Testing of hardened concrete, depth of penetration of water under pressure. Study on durability of high performance concrete with alccofine and fly ash. The hybrid fibers help to reduce the cracks due to shrinkage, creep and early age thermal cracking along with increase in ductility, toughness and fatigue resistance. The final combination is used as fiber volume fraction – 1. At the end of this time powdered samples by rotary impact hammer are obtained at various depths,mm.
Denser pore matrix restricts chloride penetration and alkalinity forms passive layer on steel and protect it from corrosion. The slabs used were water cured for 28 days. This alccoofine the concrete microstructure and enhances the degree of impermeability and the strength characteristics of concrete. The raw materials are composed primary of low calcium silicates. Alccofine when used along with recommended admixtures, have penetration characteristics comparable to chemical grouts such as Silicates and Acryl amides, without the toxicity associated with these chemical grouts.

Misconception is widely-held that high strength concretes are, per se, highly durable. High range water reducers HRWR are extensively used to ensure placement with low water contents.
Alccofine is a microfine material comprising of particles much smaller than that of regular Ordinary Portland Cement.
ALCCOFINE results in to formation of dense pore structure and inbuilt CaO provides increased secondary hydrated products because of which improved strength gain at early as well as later ages are observed. To receive any information such as third party test reports or receive a quotation from us, please feel free to send us an inquiry on info finessescm. This reduces the permeability of hydrated products to great extent slccofine protects aclcofine from chemical attack.
Skip to main content. Presently, we only cater to the Maharashtra region. Due to its unique particle size distribution and inbuilt CaOALCCOFINE results in to formation of dense pore structure, which results in improved workability, workability retention and compressive strength at all alccoflne. Compressive strength and workability of concrete specimen with constant binder and HRWR content.
