#Good Construction Practices – Terrazzo Floor


Terrazzo is described as a composite material, poured in place or prefabricated for precast terrazzo which is used for flooring, base, walls, stair treads, countertops, and other custom products. Classic terrazzo is a mixture of marble fragments, called the aggregate, and a cementitious binding agent, called the matrix.  It is resilient and can be used inside and outside, and it can be cast in place or laid in manufactured tiles. Terrazzo adds a luxurious component to both interior and exterior designs and can be used in truly innovative, sustainable ways, yet architects often don’t choose it because it can be expensive and difficult to detail.

Dividers used in terrazzo floors must be located directly over concrete joints, which should occur a maximum of three times the depth of the concrete in inches.

Concrete joints should also be detailed to run off all corridor intersections and corners and never be spaced more than 1.5 times the width of the concrete pour.

Today, about 90 percent of terrazzo being installed is epoxy-based. It is used widely because of its design flexibility, speed of install, the introduction of crack suppression membranes and overall weight of epoxy terrazzo.

Cement terrazzo is generally used for outdoor applications. That is because moisture. There should be enough vapour protection. If any old slab is very wet it will create cause issues with the terrazzo bonding to the slab. So if you want cement terrazzo, you need skilled contractor.

Poured-in-place terrazzo is one of the most durable floor systems you can purchase on the market today and one of the benefits of having poured-in-place terrazzo floors is that the terrazzo is monolithically bonded to the substrate. When terrazzo is bonded to a slab, the concrete substrate will break before the bond between the slab and terrazzo breaks. Poured-in-place terrazzo also creates a seamless floor system, which is easier to maintain when compared to a tile floor with grout joints.

Tips for Concreting in rainy season

-
Image
Concreting in rainy season is one obstruction which is tackled very carefully. Ready mix concrete gets much affected by rain if it still not reached its initial setting time. If ready mix concrete is in between its initial and final setting time than it will leave patch marks. If rain intensity is high than upper portion of ready mix concrete may get disturbed. If ready mix concrete has reached it final setting time than it turns into a source of curing of ready mix concrete. Water content should be specified for the mixture and depends on the wetness and humidity of raw material. This water-cement ratio can be reduced by mixing suitable admixtures. The use of hydrophilic crystalline admixtures when laying the concrete provides concrete with the resistance to infiltration of water under hydrostatic pressure. By using this admixture we can block pores and microcracks in the ready mix concrete thus preventing passage of water and this will decrease not only initial

Vacuum Concrete

When hardening of concrete takes place excess water should be removed otherwise it will reduce concrete strength. So Vacuum concrete the type of concrete in which the excess water is removed for improving concrete strength. The water is removed by use of vacuum mats connected to a vacuum pump. Water cement ratio is important to achieve higher strength and Workability is also important for concrete, so it can be placed in the formwork easily without honeycombing. When Workability requirement is over this excess water will evaporate and leave capillary pores in the concrete and that leads to into high permeability and less strength in the concrete. Therefore, workability and high strength don’t go together as their requirements are contradictory to each other. This technique is such way unique that it can provide to fulfil these two requirement at the same time. This technique is used in industrial floors, parking lots and deck slabs of bridges  etc.  This can be done

Techniques of Soil Improvement

-

Soilimprovement is to improve its engineering performance such as strength, reduced compressibility, reduced permeability, or improved ground water condition. There are various techniques used for the improvement of the soil based on the construction activity and type of soil. The soil improvement techniques are the following. Ø   Surface Compaction: This is process to make soil densify. Any soft and loose site needs a compacted base for lying the structure. All conventional rollers like smooth wheel, rubber-tyred, sheep foot, vibratory and grid rollers can be used. Ø   Drainage Methods: When the water presence increase that will create pore water pressure and decrease the shear strength so ground water has to be controlled. Heavy inflow of water can cause erosion. So certain methods will have to be adopted to control ground water. Ø   Vibration Methods: Vibration methods can be effectively used for rapid densification of saturated non-cohesive soils.Some of t
