What is Bitumen and its uses?

What is Bitumen and its uses?

*******

Bitumen is the binding material present in asphalt. Sometimes it is also known as mineral tar. Bitumen is produced by partial distillation of crude petroleum.

Please , tell us procedure of Bulk density of bricks?

Please , tell us procedure of Bulk density of bricks?

*******

Objective:

To determine the bulk density of bricks.

which one is better ,concrete block or brick masonry?

which one is better ,concrete block or brick masonry?

*******

Both concrete block and brick masonry are strong, fire-resistant, insect-proof building materials. They have a lot of thermal mass, which helps them retain heat and makes up for their relatively low insulation value. However, despite their similarities, block and brick have some major differences.

What does 33,43 and 53-grades of cement mean?

What does 33,43 and 53-grades of cement mean?

*******

Cement is a very important building material used in the construction industry. It’s essentially a fine powder, which when mixed with water undergoes chemical change and thereafter allowed to set and harden is capable of uniting fragments or masses of solid matter together to produce a mechanically strong material.

When and Where Pile Foundations are Used?

When and Where Pile Foundations are Used?

*******

Pile foundations are generally adopted in the following situations:

1. The sub-soil water table is very high which can easily affect other foundations.

Flow Table Test

Flow Table Test

This test was covered by BS 1881 : 105 : 1984. The test is appropriate for concrete of high and very high workability, including flowing concrete which would exhibit a collapse slump.

What is meant by 80/100 grade bitumen?

What is meant by 80/100 grade bitumen?

*******

A 80/100 grade bitumen indicates that its penetration value lies between 80 & 100.Grading of bitumen helps to assess its suitability in different climatic conditions and types of construction. For bituminous macadam and penetration macadam, IRC suggests bitumen grades 30/40, 60/70, 80/100.

What are the different types of Loads on Structures?

What are the different types of Loads on Structures?

*******

The types of loads acting on structures for buildings and other structures can be broadly classified as vertical loads, horizontal loads and longitudinal loads. The vertical loads consist of dead load, live load and impact load. The horizontal loads comprises of wind load and earthquake load. The longitudinal loads i.e. tractive and braking forces are considered in special case of design of bridges, gantry girders etc..

How to calculate specific gravity of cement?

How to calculate specific gravity of cement?

Using Le Chatelier Flask method, we can determine this value. This is an experiment conducted at the site level.
