5 FUNCTIONAL REQUIREMENTS OF FORMWORK FOR CONCRETE STRUCTURE
Essential requirements of formwork are it should be strong enough to take the dead loads, live loads, incidental loads and other loads expected during construction before attaining the strength by the concrete.
5 FACTS OF CEMENT MORTAR EVERY SITE ENGINEER SHOULD KNOW.
Mortar is a homogeneous mixture, produced by intimately mixing cementitious materials, water and inert materials, such as sand, to the required consistency for use in building together with masonry units.
4 TYPE OF ROCKS THAT CHALLENGE TUNNEL ENGINEERS
In last few years, lot of tunneling works are being executed in all over the world. One of the toughest challenge engineers face during design and construction phase is to deal with geology of that area.
PROCEDURE FOR LAYING AAC BLOCK MASONRY WORK [A HOW TO GUIDE]
ACC block stands for autoclaved cellular concrete block. The ACC block is a valuable addition to the masonry units accessible to masonry contractors. Advantages of cellular concrete block masonry over brick masonry are its lightweight design, minimal mortar use, and faster working speeds Many contractors are unfamiliar with the usage of autoclaved cellular concrete blocks. … Read more
WATER PROOFING TREATMENT OF ROOF SLAB [A STEP BY STEP GUIDE]
Water Proofing Treatment of Roof Slab In this method polymer modified cementitious slurry coatings are applied over the base concrete. This technique of waterproofing is latest development in the field of waterproofing. Polymer imparts significant improvement in impermeability. Polymer modified cementitious slurry has coefficient of expansion very similar to concrete thereby it does not get … Read more
4 FUNDAMENTAL FACTORS TO CONSIDER DURING CONCRETE MIX PROPORTIONING
The process of selecting concrete mixture proportions is a process of optimization of several desirable characteristics based on the project requirements. The characteristics to be optimized are economy, strength, durability, and placeability. 1. Economy. The primary reason for systematically determining mixture proportions is economy. The maximum economy can be achieved by minimizing the amount of … Read more
7 FACTORS INFLUENCING REBOUND HAMMER TEST OF CONCRETE
Rebound Hammer Test The Schmidt rebound hammer is principally a surface hardness tester with little apparent theoretical relationship between the strength of concrete and the rebound number of the hammer. However, within limits, empirical correlations have been established between strength properties and the rebound number. Further, scientist has attempted to establish a correlation between the … Read more
AN INTRODUCTION TO CEMENT CONCRETE FOR BEGINNERS
CEMENT AND CONCRETE – ARE THEY THE SAME? Many people think that cement and concrete are the same product – they are not. Cement is a dry powdered chemical that, when mixed with water, slowly reacts to form a new hard, solid compound. On the other hand, concrete is a mixture of cement blended with … Read more
5 TYPES OF ERRORS IN CHAINING AND WAYS TO MITIGATE IT
Errors in Chain Surveying Every measurement made with a mechanical device is subject to any error that could possibly be caused by the condition of the device or by the procedure used in taking the measurement. Some of the more common sources of errors are the standards to which the chain was manufactured, any damage … Read more
