Fineness of cement is another quality control parameter that experts keep in check of at the laboratory. The size of the particles of OPC impact the surface area and the heat of hydration. I’ve already explained the definition in my previous article on different physical properties of cement. So, if would reproduce my answer to … Read more
When your work involves overhauling public installations or buildings, there is a certain amount of pressure behind you. This is something that people have a certain association with, and your aim is to improve it without making it something unrecognizable – or somehow robbing it of an aspect that people value. Identity, however, is quite … Read more
Water is an important ingredient of a concrete mix and water cement ratio is an important factor in concrete or cement mix design. While working at site, concrete workers always try to add water in it so as to increase the workability of concrete but actually they are reducing the strength and durability of concrete. … Read more
Water replacement method is used for determination of field compaction or field density of soil and gravely fills. The method is used for soil fills containing particles larger than 75 mm such as earth embankments, road fills, or structural backfills. The test method is standardized per ASTM D5030. As I’ve explained in my earlier posts … Read more
Knowing about various types of cement and their unique set of behaviors would allow you to opt the appropriate one for your construction needs. Actually the amount and proportion of various ingredients and components of cement are varied. In my previous post, I have talked about Bogue’s compounds of cement. These compounds including C3S (Tri-calcium … Read more
Core cutter method is a type of field density test performed to evaluate the in-situ density of cohesive or clayey soils. It is a very easy and simple test that includes driving of a steel core-cutter with sharp blades into the fill. So, this method is not suitable for coarser soils as the core may … Read more
Maximum dry Density of soil is determined in the laboratory with the help of Standard Proctor Test standardized by ASTM D698 and AASHTO T99. So this read explains in depth, the significance, background, apparatus and procedure of the standard proctor test. Basics of Soil Compaction It is worth mentioning, that densification or compaction of soil … Read more
Generally, plenteous useful properties of bricks exist making it the widest used and most popular construction material. Its resilient and sustainable characteristics against forces of nature are not new or not unknown. Among brick properties, there are some basic ones which are related to the physical character and there are some additional properties that describe … Read more
Although different types of stone masonry were in use from ancient times for construction of hideouts and houses, but owing to the durability and sturdiness they still are a popular choice among construction peers. Can you imagine, if the great Egyptian pyramids would had built by bricks, could had survived till now? In fact, most … Read more
Bogues compounds are responsible for initial setting of the cement grout. These compounds have been researched extensively by an American chemist named Rober Herman Bogue (R.H. Bogue) who is well known for his books on The Chemistry of Portland Cement and the Chemistry and Technology of Gelatin and Glue. After his extensive research, Bogue has … Read more
