ALCCOFINE 1203 is a specially processed product based on slag of high glass content with high reactivity obtained through the process of controlled granulation. The raw materials are composed primarily of low calcium silicates. The processing with other select ingredients results in controlled particle size distribution (PSD). The computed blain value based on PSD is around 12000 cm2/gm and is truly ultra fine. Due to its unique chemistry and ultra fine particle size, ALCCOFINE 1203 can also be used as a high range water reducer to improve compressive strength or as a super workability aid to improve flow.
Alccofine is a specially processed product based on slag of high glass content with high reactivity obtained through the process of controlled granulation. Alccofine have used conforming to ASTM C989-99. Physical and Chemical Properties,
Alccofine 1203 could be an especially prepared product support scoria of additional glass content with more reactivity acquire through the method of restricted required degree of fines. Owing to its unique chemistry and ultra fine particle Study on New Supplementary Cementitious Material in Construction of Green Building (IJSRD/Vol. 4/Issue 05/2016/295) All rights reserved by www.ijsrd.com 1197 size Alccofine 1203 is proprietary low calcium silicate based mineral additive. Controlled granulation process results in unique particle size distribution. Its latent hydraulic property and pozzolanic reactivity results in enhanced hydration process. Addition of Alccofine 1203 improves the packing density of paste component. This results in lowering water demand, admixture dosage and hence improving strength and durability parameters of concrete at all ages.
The controlled particle size distribution (PSD) comprises of 0.1 to 17 micron size particles. The computed blain value based on PSD is around 12000cm2/gm and is truly ultra-fine. Due to its unique chemistry and ultra-fine particle size, ALCCOFINE 1203 provides reduced water demand for a given workability.This results in either high values of slump or reduction in admixture dosage or reduction in w/c ratio. In turn this improves the compressive strength and compactness values of concrete mix.
In addition to its unique PSD, Alccofine 1200 series, due its reactive contents, works HYDRAULICALLY in the concrete mix. It maintains alkalinity of the mix and helps in resisting chloride, sulphate and carbonation attack. It enables the higher level of replacement of OPC with pozzolonic materials like fly ash & GGBS. This results in more durable concrete structures without increasing the cost.
Due to dual reaction nature (pozzolanic + hydraulic), coupled with unique Particle Size Distribution; Alccofine 1200 series is the best choice for economical, high strength, robust & durable concrete mixes. It helps in improving pump-ability of concrete mixes containing 100% crush sand.
Alccofine additives are part of the concrete used in metro rail, tunnels, dams, roads, bridges, high rise constructions, etc. and is becoming a preferred choice as a premium micro fine mineral additive for modern day.
AAKAAR aims at creating a platform to compete, learn and promote Civil Engineering amongst the education fraternity through Competitions, Events and ICES, IIT Bombay (research paper conference) and also to make a festival of all and for all the Civil Engineering students.
