Silica fume is a by-product of silicon metal production that improves the properties of concrete by acting as a microfiller to enhance bonding and reduce permeability. The concrete mix design utilizes 3% silica fume and 97% ordinary Portland cement. It also includes the admixtures MasterGlenium ACE 8538 superplasticizer for workability and durability, MasterLife CI30 accelerator and corrosion inhibitor, and SikaFume cementitious material. Using silica fume and admixtures improves the sustainability of concrete by reducing CO2 emissions from cement production and increasing the service life through higher strength, impermeability and durability.
FAIRPLAST IPS is a powder form integral water proofing additive for mortars, which ensures perfect water tightness. It can be used for various applications like external plaster, water tank plaster, sunk slab plaster etc. FAIRPLAST IPS entrains the air into the mortar which fills up the capillaries into the mortar and ensures the perfect water tightness. It is waterproofing admixture to fill natural pores within the concrete or mortar.

FAIRFLO SCA is a differentiated from conventional superplasticisers in that it is based on a unique carboxylic ether polymer with long lateral chains. This greatly inproves cement dispersion. At the start on the mixing process an electrostatic dispersion occurs but the cement particles capacity to separe and disperse. This mechanism considerably reduces the water dement in flowable concrete. FAIRFLO SCA combines the properties of water reduction and workability retention. It allows the production of high performance concrete and / or concrete with high workability. FAIRFLO SCA is particularly strong superplasticiser allowing production of consistent concrete properties around the required dosage.

Classification Of Aggregates, Good Qualities of an Ideal Aggregate: ,Tests on Aggregate:- , Specıfıc gravıty of Aggregate. , Flakiness & Elongation Index , Fineness Modulus (f.m):
Lesson: Concrete Technology - Building Materials
The quality of aggregate affect the durability and strength of concrete. Since about 3/4 of the volume of concrete is occupied by aggregate.
Introduction to admixtures. Standard code definition of admixtures and additives. Various types of admixtures and additives along with their properties. Mechanism for working of admixtures and additives. Effect of admixtures of properties of concrete.
Concrete is one of the most versatile materials used in infrastructural development. It plays a critical role in in construction industry and making it sustainable is of paramount importance. How do we do it? Let us look here!!
Geopolymer bricks are the new innovation in the field of brick industry. Geopolymer bricks contain fly ash as the source material and an alkaline activator for the activation of polymerization reaction.experimental work is supposed to be performed on geopolymer bricks with fly ash and GGBS as source materials and sodium hydroxide and sodium silicate as an activator. It reduces dead load on structures due to light weight (2.6 kg, dimension: 230 mm X 110 mm X 70 mm).
Analysis of Admixtures and Their Effects of Silica Fumes, Metakaolin and PFA...IJMER
This paper presents a review of the properties of fresh concrete including workability, heat
of hydration, setting time, bleeding, and reactivity by using mineral admixtures fly ash (FA), silica
fume (SF), ground granulated blast furnace slag (GGBS), metakaolin (MK), and rice husk ash (RHA).
Comparison of normal and high strength concrete in which cement has been partially supplemented
by mineral admixture has been considered. It has been concluded that mineral admixtures may be
categorized into two groups: chemically active mineral admixtures and microfiller mineral
admixtures. Chemically active mineral admixtures decrease workability and setting time of concrete
but increase the heat of hydration and reactivity. On the other hand, micro filler mineral admixtures
increase workability and setting time of concrete but decrease the heat of hydration and reactivity. In
general, small particle size and higher specific surface area of mineral admixture are favourable to
produce highly dense and impermeable concrete; however, they cause low workability and demand
more water which may be offset by adding effective super plasticizer.
In this construction world, Geopolymer concrete is a special concrete which doesn't
requires the Ordinary Portland Cement and also reduces the emission of carbon-dioxide. The
Geopolymer Concrete is made up of industrial by-products (which contains more Silica and
Alumina) and activated with the help of Alkaline solution (combination of sodium hydroxide &
sodium silicate or potassium hydroxide & potassium silicate). The high viscosity nature of
Geopolymer Concrete had the ability to fail due to lack of compaction. In improvising the
issue, Self Compacting Geopolymer Concrete has been introduced. The SCGC doesn't require
any additional compaction it will flow and compacted by its own weight. This concrete is made
up of industrial by-products like Fly ash, GGBFS and Silica Fume and activated with alkaline
solution. The earlier research was mostly on Fly ash based SCGC. In few research works Fly
ash was partially replaced with GGBS and Silica Fume. They evaluated the compressive
strength of concrete with varying molarties of NaOH; curing time and curing temperature. The
flexural behavior of the concrete also examined. The Fly ash based SCGC was got high
compressive strength in heat curing as well as low compressive strength in ambient curing.
The presence of GGBS improves the strength in ambient curing. For aiming the high strength
in ambient curing Fly ash will be completely replace and examine with different mineral
admixtures.

3. QUANTITY OF MATERIALS
Silica fume is a by-product of silicon metal production that is
generated in large quantities. Utilization of this by-product in
concrete may solve the problems relating to disposal,
environmental pollution and health hazards.
The manufacturing of Ordinary Portland Cement (OPC) also
produces up to 0.8 kg of CO2 per kg of finished cement. By
replacing OPC with other pozzolans such as silica fume, CO2
production can be reduced.
MasterLife CI 30 accelerator works as a corrosion inhibitor and
this improves the durability of concrete, resulting in longer
service lives of concrete structures. MasterGlenium ACE
superplasticizers is also known to improve concrete durability.
