What is slump of Concrete? Types – Factors effecting Slump

If you’re bit concerned about quality of freshly mixed concrete, you’d be dealing with terms like slump of concrete, consistency, fineness of cement, and compressive strength. Of all, slump of concrete is an important quality control parameter. The next time you step in as incharge of concrete pouring activity, you should know different types of … Read more

Curing of Concrete – Methods – Temperature – Stages – Importance

Curing of Concrete

You might have heard about concrete curing, a process of spraying water on freshly placed concrete. But probably have not  heard about other methods of curing of concrete like using water-soaked hessian cloth or ponding. But do you know why concrete needs curing? Why curing is so important for the longevity and durability of concrete? … Read more

Fineness of Cement by Blaine’s Air Permeability test

Blaine's Air Permeability Test

Air permeability test or Blaine’s air permeability method is one of the most accurate methods of finding the fineness of the cement. In this method, we determine fineness of the cement with the help of an apparatus patented by LEA and NURSE, it is done by the NURSE and BLAINE’S method as, apparatus consists of … Read more

Difference between Cement and Concrete or Mortar

Difference between Cement and Concrete

As there’s a big difference between cement and concrete, you’re at times confused what to use. You want to fix an old stone wall or maybe a brick sidewalk, it’s easy right! Just go down to the Home Center pick up a bag of cement or is it concrete no wait maybe mortar. Well, many … Read more

Compaction factor test for workability of concrete

Compaction Factor Test

The compaction factor test is done to check the workability of concrete, on the basis of weight ratio between partially compacted to fully compacted concrete. We can’t use the slump test for low workable concretes. Concretes we mostly use in mass dam structures or road pavements have significantly low values of slump. For all such … Read more

Specific Gravity of Cement – Definition – Test – Procedure

Specific Gravity of Cement

For most of the cements we use in construction has a specific gravity of cement ranging between 3.1 to 3.16 g/cc and a density of 1440 Kg/m3. But that doesn’t mean it stays same for all types of cement we have. Moreover, specific gravity itself is an important quality control parameter for cements while determining … Read more

Falsework – Types of Falsework – Applications – Components

Uses of Falsework

If you’re constructing a bridge, you will support the deck with a temporary structure until it can sustain. Wouldn’t you? That is what falsework is. Well, a temporary support to a permanent structure, material, or plant during construction is what we define as falsework. So, in today’s read I’ve skimmed through every bit of detail … Read more

Dry density of soil – Relationship of dry density with moisture content

Maximum Dry Density of Soil

Dry density is an important concept in geotechnical engineering. When you’re in the field for soil compaction, you need to know the parameters that affect the dry density of soil. You might also be looking for related terms like dry unit weight of soil, bulk density of soil, or density of soil solids. Definition of … Read more

Slump Test Experiment – Apparatus – Types – Procedure

Slump Test Experiment

Slump test is a laboratory or site experiment civil engineers perform to assess the workability of the concrete. With such, the test is also referred to as slump cone test or concrete workability slump test. During concrete pouring, you need to check the uniform quality of concrete in terms of consistency and workability. Fresh concrete … Read more
