How to Improve the Bearing Capacity of Soil

How to Improve the Bearing Capacity of Soil?

The ultimate bearing power or ultimate bearing capacity of a soil is the minimum load per unit area, which causes failure to the soil. It is known that a load of any structure is finally transmitted to the soil lying below the foundation of the structure. Hence it is very essential to know the strength and behaviour of the underlying soil. Bearing capacity of the soil is its ability to support the load coming over it per unit area without causing excessive settlement and displacement.

Quantity analysis for Materials In 1 cu.m Cement Concrete

Quantity analysis for Materials In 1 cu.m Cement Concrete

Concrete is basically a heterogeneous mixture, which consists of cement, sand, stone aggregates and water. For a big project, where the higher grade of concrete is used, mix design is must to determine the quantities of the materials required to maintain the grade. But when a lesser grade of concrete is used, quantity analysis for Cement, Sand And Aggregate is done by some basic calculation.

Behavior of Cement Concrete Using Recycled Concrete Aggregates

The requirement of concrete aggregate in India is large. Corresponding to the current annual production of cement of 300 million tons, total requirement of coarse and fine aggregate for use in cement concrete, mortar and plasters of about 1500 metric tons per year is a safe estimate. There is difficulty in obtaining natural aggregates within economic distances. Search for alternate sources of aggregates thus assumes importance. One such alternative is recycled concrete aggregate derived from construction and demolition wastes, which allow conservation of natural resources and land.

Transportation contributes to the economic, industrial, social and cultural development of any country. Transportation is vital for the economic development of any region since every commodity produced whether it is food, clothing, industrial products or medicine needs transport at all stages from production to distribution. The inadequate transportation facilities retard the process of socio-economic development …

How To Classify Rocks For Engineering Purpose

Have you ever thought about how to classify rocks for engineering purposes?? Aggregates are one of the most important materials in civil engineering. Basically, Construction aggregate, or simply “aggregate”, is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. They give …

Flash Point and Fire Point Tests of Bitumen

Flash Point and Fire Point Tests of Bitumen

Flash point of bitumen is the temperature at which, its vapour will ignite temporarily during heating when a small flame is brought into contact with the vapour. The knowledge of this point is of interest mainly to the user, since the bitumen must not be heated to this point. The flash point tells the critical temperature at and above which suitable precautions are required to be taken to eliminate the danger of fire during heating. This temperature, however, is well below that at which the bitumen will burn. The latter temperature is called the fire point.
