Fire Bricks




It is made using fire clay and has a good resistance against high temperatures. This bricks can be used in kilns, lining surfaces, fireplaces and fireboxes. Fire bricks are manufactured similar to that of normal bricks but not in during the burning process. These bricks can exposed to very high temperature.

Fire clay is used to make fire bricks. There are main two components in clay, silica and alumina. In that silica percentage should be around 60-70% and alumina should be around 25-35%.
Fire clay can be divided in three types and that is based on fire resisting capacity.

Ø  High-grade fire clays
Ø  Medium-grade fire clays
Ø  Low-grade fire clays
Fire bricks are available in yellowish white and white colour. It also has a good chemical resistance.
Fire bricks are three types.
Ø  Acidic fire bricks: These fire bricks are used to resist chemical acidic actions against chemicals.
Ø  Basic fire bricks: These fire bricks are good at corrosion resistance and chemical resistance.
Ø  Neutral fire bricks: These bricks are good enough to withstand against acidic fumes and corrosive actions.

Uses of fire bricks

Ø  These are used for Inner surface lining of kilns, furnaces, chimneys etc.
Ø  These can be used for inner-lining of wood-fired ovens.
Ø  It is used in fire resistance structure and so structures are protected against fire accidents.
Ø  It can be used as an insulating material.

Coarse Aggregate and its effects in Mix Design of Concrete

Image
Coarse aggregates are one of the main components of mix design and it has a large volume in mix design of concrete. That is why it greatly af fects the concrete mix design. Its property like strength, size, shape, water absorption capacity influence the demand of water, cement and fine aggregates in mix design. High maximum coarse aggregate size will provide lower demand of water because this aggregate has lower surface area compare to small aggregate size. Rounded shaped aggregates provide economical mix design for normal concrete. Angular coarse aggregates are used in high strength concrete. Higher aggregate strength would produce higher concrete strength. Maximum size of coarse aggregate will give the idea about water demand and quantity of fine aggregate in mix design. It will improve workability. Higher maximum size of aggregate lower the surface area and lower aggregate provides large surface area. If surface area is more water demand is higher and surface area i

Uses of Rice Husk Ash in Building Construction

Image
Rice husk ash can be used as a substitute for Portland cement which reduces the cost of concrete and other use is that it can be used in production of high strength concrete. There are many applications of rice husk ash in the construction such as high-performance concrete, insulation, green concrete, bathroom floors, industrial factory floorings, waterproofing and rehabilitation, and it is also used ceramic glaze and roofing shingles. Applications of Rice Husk Ash in Building Constructions Low cost building blocks When low cost building is constructed, rice husk ash is used instead cement. As cement is expansive component of concrete and for low cost building it is not affordable to use so rice husk came in picture. It is demonstrated that, replacing 50% cement with rice husk ash would reduce cost of concrete by 25%.An Indonesian company has used mix proportion of 10% cement, 50% aggregate and 40% RHA plus water to produce blocks. The average strength of the block

Ultra High Performance Concrete

Image
This concrete has minimum strength of MPa. It has a great durability. C ommonly, the UHPC consists of cement, silica fume, fine quartz sand, high range water reducing admixtures, steel fibers, and low water to cementitious materials ranging from 0.15 to 0.25. Durability of this concrete is superior compared to ordinary concrete as its pores are discontinuous, which declines liquid penetration. UHPC is used to improve concrete homogeneity through the removal of coarse aggregate in the mixture. It does better gradation and mixture between the main components so that voids are reduced thus density increases. Steel fibres are added to the mixture to avoid brittleness of concrete. Main components in UHPC are Portland cement, Silica Fume, Limestone and or quartz flour, Fine sand, High-range water reducers, Water and Steel fibres. Compressive strength of UHPC is ten times higher than ordinary concrete. Tensile strength of about 10 MPa. UHPC has properties similar to hard r
