Quality Documents and Their Control

Documents are part and parcel of any construction project, be it a small, medium or a large one. Large projects like industrial and realty construction projects usually comprise of a number of departments working in co-ordination with one another and most of them generates a considerable volume of documents. One of the highest document producing … Continue reading

12 Easy-to-remember Steps for Designing a Concrete Mix

Mentioned below are twelve simple steps for designing any standard concrete mix as per Indian Standards. For mixes of very high strength (say, M60 and above) there may be special requirements over and above these steps or special design procedures itself. These easy-to-remember steps were derived by the author from the on-site mix design procedure … Continue reading

Some Important Quality Control Tests Commonly Conducted at Construction Sites

Many and assorted quality control tests are conducted regularly in the quality control laboratories at various construction sites. The types and quantum of tests conducted depend on factors like the type of project, size of the project, the degree of importance laid on the quality domain, budget for the project and so on. For example, … Continue reading

Quality Control Tests on Commonly Used Clay Bricks – Part B

Contd. from Part-A ….. b) Efflorescence test : Conventional clay bricks may contain some amount of alkaline substance in them. However, the greater the presence of such content the greater the risk of efflorescence which appear in the surfaces of bricks as fine whitish layers (deposits). These are hard to control and can lead to … Continue reading

Quality Control Tests on Commonly Used Clay Bricks – Part A

Bricks are undoubtebly amongst the most commonly used construction materials anywhere. Incidentally, concrete is regarded as the most used construction material in the world in terms of weight or volume according to some estimates. Knowing a few simple yet important quality related details as well as about few quality tests on this widely used construction … Continue reading

Quality Control in Project Sites

Quality Control in any project construction site is as important as any other project related activity such as design, execution (of construction activities), planning and so on. Quality control succeeds quality assurance. QA & QC have already been discussed in good detail in one of the earlier posts. This site has a number of useful … Continue reading

In fact, these two are integral parts of virtually any project one can think of. Proper implementation of Quality Assurance and Quality Control not only results in a sound project … Continue reading

Concreting in Cold Weather

Hot weather concreting was discussed already in a couple of earlier posts. Like concreting in hot weather, concreting in cold weather too calls for special care. A brief discussion on the same finds place herein. When the temperature of a concrete mix is quit low the rate of setting or gaining strength for the concrete … Continue reading
