Soundness test on Aggregate | Sample selection and procedure

Soundness test determines the disintegration of aggregates due to weathering. This includes freezing, thawing, marine condition etc. However, the weak and porous aggregate shows a change in weight during this soundness test.

Soundness Test on Cement: Procedure and Significance

The soundness of the cement is the ability to resist volume changes after hardening. The soundness test on cement is significant because,using unsound cement leads to cracks and hamper the structural quality. A sound cement is one of the key materials used in construction. Therefore it is essential to determine its quality before using it in construction. 

Specific Gravity and Water absorption test on Aggregate

Specific gravity and water absorption test are significant tests on aggregates. Perhaps aggregates are the fundamental and essential components of concrete and play a significant role in the design mix of concrete. More than 70 to 80 per cent of the volume of concrete is aggregate. Hence the water absorption and specific gravity test are essential and significant tests .

What is Tertiary Wastewater Treatment? – Top Physicochemical Methods Explained

Tertiary wastewater treatment, also known as advanced wastewater treatment, is the third step of wastewater treatment. After secondary treatment, tertiary treatment of effluent entails several extra procedures to minimise organics, turbidity, nitrogen, phosphorus, metals, and pathogens. Tertiary treatment of wastewater makes it ready for reuse. Some examples of reuse include:

Tunnel Engineering- Definition, Study Modules Guide

Tunnel engineering is a branch of civil engineering that deals with construction of tunnels. There is much more to know about the amazing sector. Needless to say, no tiny virus can be a reason to prevent us from transporting for essential purposes. Therefore, the career opportunities are always out there for you.

Land pollution Effects on Human Health and Nature

Land pollution has disastrous effects, particularly on the survival of animals and humans, as well as in the quality of soil and water. Human activities have increasingly ruined and degraded land since the dawn of industrialization, producing diseases in humans and animals and limiting the capacity to support ecosystems and varied life forms.

How a Landfill Works? Understanding Process, Operation, Life cycle

Landfills are a regular occurrence all over the world, owing to the rising volume of trash generated by our homes, schools, offices, hospitals, and markets. The rising number of landfills around the world is largely due to increased urbanization and population growth rates.

Types of Levelling – Uses and advantages

Types of levelling – Leveling is a branch of surveying that deals with computing and determining the relative heights between different points with respect to the datum. The purpose of leveling is for determining the elevation of a point and establishing the same at a given elevation. Moreover leveling deals with the computation of measurements in the vertical plane. There are different types of leveling in Surveying. In this article, we will discuss the purpose and types of leveling.

The Ozone Layer Depletion – Effects and Causes

The ozone layer is an area of the earth’s stratosphere that contains high levels of ozone (O3) and protects the planet from the sun’s harmful ultraviolet rays. It can absorb roughly 97-99 percent of the sun’s damaging UV radiation, which otherwise can kill life on the Earth.

Penetration Test for Bitumen – Significance and Procedure

The penetration test for bitumen is a laboratory method for grading bitumen based on its hardness. In this test, the amount of penetrating a specific needle into the bitumen is measured.

More than 85% of bitumen is used in road construction. Weather condition affects on bitumen binder. In cold weather, bitumen becomes hard, and the possibility of cracking increases. On the other hand, hot weather causes bitumen becomes soft and sticky.
