Dynamic Compaction


This compaction type for soil improvement is an efficient and cost-effective technique. In this technique dynamic effect of high energy collisions on weak soil to make it more dense. This is generated by dropping a static weight from a defined height.

In this steel box, concrete or reinforced mass concrete are lifted through the cranes and released it repeatedly from a certain height. This dropping will bring vibrations on soil into play and improves it at a depth. Dynamic compaction is used to improve weak soil such as loose medium to coarse grained sand with salt or clay content. This improves the depth of about 10m but its impacts reach till 12m depth.

The purpose of dynamic compaction technique is to transmit high energy waves through a compressible soil layer to improve Geotechnical properties of soil at greater depths. This concept is simple but required experienced engineers. This reduces air and water voids between soil particles.

Advantages of dynamic compaction

Ø  It compacts and densify soil till 12m.
Ø  It is effective in various soil condition.
Ø  It improves bearing capacity of soil.
Ø  It decreases the volume of landfill waste.
Ø  Post-construction settlements are reduced. 
Ø  This technique is cost effective and environment friendly.
Ø  Dramatic cost savings in excess of deep foundations and most undercut and replace options.

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
