What are the Types of Masonry Walling Materials? [PDF]
Walls are a significant building component that encloses or divides a building and forms the periphery of a room. A wall supports the weight of the roof/slab and the floor and provides shelter from external commotions. It constitutes most of ...
How to Prevent Excavation Problems through Good Construction Practices? [PDF]
Excavation problems during construction usually emerge due to unfavorable groundwater conditions, inclement weather conditions, and slope instability. Proper control of groundwater is critical in the excavation process as it can make other issues such as slope instability less severe. One ...
How to Drive Timber Piles into Ground? [PDF]
Timber piles are used extensively for compaction of soils and for supporting and protecting waterfront structures. The choice of use of timber piles is mainly governed by the site conditions, particularly water table conditions. Timber piles are comparatively light for ...
How to determine Depth and Number of Boreholes for Geostructures? [PDF]
The determination of adequate number and sufficient depth of boreholes is critical to gather enough data for the design and construction of geostructures such as foundations, bridges, retaining walls, cut slopes, and embankments. There is no specific rule to determine ...
Tunneling Failures – Causes and Remedies [PDF]
Tunneling is one of the most intricate and expensive projects in engineering and construction. With increasing demands and the emphasis on reducing the travel time between any two places becoming a priority, the risks and challenges involved in the construction ...
How to Perform Maturity Test on Concrete? [PDF]
The maturity concept uses the time/temperature history of concrete to develop a maturity-strength curve that is specific to a mix. The curve thus generated helps estimate the in-place early-age compressive (and flexural) strength of concrete during construction. Several methods are ...
How to Safely Erect Structural Steelwork? [PDF]
The purpose of following safety precautions while working with structural steel is to mitigate health and safety risks for all workers associated with the erection of steel structures. Safety for Men The men assigned for the job should undergo a ...
How to Conduct Blasting Operations Safely? [PDF]
Blasting is a process of reduction of rocks or hard soil into fragments with the help of explosives. The blasting operation involves drilling of holes, installation of a detonator and charge, detonating the charge, and removal of debris. In this ...
How to Estimate Strength of Concrete through Maturity method? [PDF]
The maturity of concrete is determined by a non-destructive approach, where the compressive strength at early ages is detected to conclude about the maturity. This test is conducted on an in-place real-time concrete mix at the site. The use of ...
