Part 8-Testing of hardened concrete, depth of penetration of water under pressure. The processing with other select ingredients results in controlled particle size distribution Alccpfine. Crushed Basalt rock was used as coarse aggregate and local river sand was used as fine aggregate. Indian Society of Education and Environment No: Log In Sign Up.
Ambuja Cement introduces Alccofine and for concrete industry
Novaka J, Kohoutkova A. At the end of this time powdered 2103 by rotary impact hammer are obtained at various depths,mm. Help Center Find new research papers in: This booklet presents results of examination carried out on ALCCOFINE in comparison with Silica Fume in concrete, and the effect it has on workability, water requirement, admixture requirement, strength and durability.
Elevated temperatures effects on HSC. In this methodology, the binder content and admixture content were kept constant and the outcome on water requirement, workability and compressive strength were measured.
International Journal of Structural and Civil Engineering. The final combination is used as fiber volume fraction – 1. 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.
Physically the product is unique with regards to its particle size distribution. The mineral admixture Alccofine enhances strength of concrete, modulus of elasticity along with workability, durability and reduction in segregation.
Article Tools Print this article. Such concrete suffer from two major weaknesses. Chloride content of the sample from each depth alccofinr determined and reported.
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. Email this article Login required. The decrease in water demand is because of high glass content which has water repelling property.
Under durability water permeability and chloride penetration were measured most commonly. Post a Comment Login required. 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 ages. In fact concrete slump is seen to be a,ccofine, due to the dense packing of cementitious material, producing low void content.
Ambuja Alccofine , Alccofine – Owndust India, Kolkata | ID:
This reduces the permeability of hydrated products to great extent and protects concrete from chemical attack. ALCCOFINE is a specially processed product based on slag of high glass content with high reactivity obtained through the process of controlled 11203. Enter the email address you signed up with and we’ll email you a reset link. Thus, it reduces the penetration of chlorides in concrete and protects embedded steel from corrosion.
Ambuja Alccofine 1203
We supply pozzolanic fly ash from various sources to cater and suit the needs of the batching units requiring fly ash. In high performance concrete applications, Silica Fume is generally proposed as the appropriate cement extender where high strength, low permeability are the prime requirements.
Durability aspects of standard concrete. The slabs used were water cured for 28 days. 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. We supply both in bulk and bag form. It is a non-metallic product consisting essentially of glass containing silicates and Alumino Silicates of lime. Fire response of hybrid fiber reinforced concrete to high temperature.
In spite of its high fineness it does not increase water demand at the dosage range of 5 to 15 percent of normal OPC in general. Development and application of hybrid fiber reinforced concrete.
Title of ASTM C ASTM C says that this test method is applicable to types of concrete where correlations have been established between this test procedure and long term chloride penetration by ponding method.
Misconception is widely-held that high strength concretes are, per se, highly durable. Secondary hydrated products formed due to pozzolanic and Cementitious hydration reaction fills the pores. It is extremely difficult to obtained proper workability, and to retain the workability for sufficiently long period of time with such concrete mixes. Site powered by Weebly. Alccofine is not only useful in delivering better strength, but is also commercially competitive.
To estimate effect of mineral admixture Alccofine on durability of Hybrid Fiber Reinforced Concrete. Thus concept of strength through durability become essential.
This refines the concrete microstructure and enhances the degree of impermeability and the strength characteristics of concrete. We are proud alccofune of Alccofine The average particle size of Alccofine is 4 to 5 microns; the top size d90 is only 10 microns. Skip to main content. 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.
