Topfit Brick - Innovative Foam Concrete Brick

7 Advantages of Topfit Brick

1)Stable

Topfit Brick is composed of cement, slag, sand, water, admixture and air, thus belongs to both air hardening and water hardening materials. It is then further stabilized by pressured steam curing to promote and complete the chemical reaction of concreting, achieving high strength and stability.

2)Light Weight, reduction in Construction Costs

Topfit Brick's normal density ranges from 1,100kg /m3 ~ 1,300kg /m3, which weighs 2/3 of clay bricks and mortar bricks, and 1/2 of in-situ concrete. With Topfit Brick, weight of walls becomes lighter, and consequently the weight of the static self-load of the building itself. Consequently, quantity of foundation and columns will decrease, consumption of reinforcing steel and concrete will lessen, reducing the overall construction costs

3)Reasonable Design and Increase Net Area of Building

4) Water proofing, Non-permeability

5)High Compressive Strength
Subject to different building's design requirements, compressive strength and density of Topfit Brick can be varied. Heat Insulation Brick: density 400 -600 kg /m3, compressive strength 0.5-1.5 Mpa; Wall Brick: density 1,100 -1,300 kg /m3, compressive strength 3.5-10 Mpa. All these specifications completely satisfy the structural requirements of general buildings. (See the specifications for details).

6) Better Sound Insulation

7)Heating Insulation, Fire Resistance
Topfit Brick possesses superior heat insulation characteristic. It is made of non-flammable raw materials, together with its micro-pored structure, enhancing its higher heat insulation and fire resistance to other wall materials. A 100mm thick wall has a fire resistance limit exceeding 4 hours

Raw Materials of Topfit Brick

High quality cement, slag, river sand, water, admixture and air

Requirements for Bricklaying

1. The bricklaying method for Topfit Brick is the same as that of traditional clay bricks. Two anchoring rods of 6 mm with length not less than 500 mm should be installed at 500 mm intervals between wall and column.
2. There is no special requirement for mortar in application. Ordinary cement mortar or cement sand mix is suitable.
3. Topfit Brick can be nailed, drilled, chiseled and accommodates expansion bolts.
4. Spray with water 1 day in advance of laying Topfit Brick. Instant spray and layis prohibited.
5. Laying height should not exceed 1.5 m per day.
6. Final laying works ( 200 mm of wall beneath the beam or roof) should be laid at least 7 days later when the original wall is rigid and stable. The bricks must be placed rigidly agains
