Concrete

Cold joints are one of the most common quality issues encountered during concrete placement. They occur when fresh concrete is placed against concrete that has already begun to set, preventing the two layers from bonding into a single, monolithic element. Although a cold joint doesn’t always necessarily mean a structural failure, it can reduce strength, increase permeability, and create long-term durability concerns. Understanding Initial Set […] Read More

Freshly poured concrete hardens within a few hours but needs about four weeks to reach full design strength. In multistory cast-in-place buildings, this waiting period can delay construction schedules, so engineers often remove formwork earlier and use shoring and reshoring to safely transfer loads to lower floors that have gained more strength. With proper planning, floor cycles can be reduced to about two weeks. Shoring […] Read More

This is one of the posts in a series of our posts that we discuss failures. Also check out the other posts in constructmagazine.com, where we discuss failures in different contexts of civil engineering. A Brief Introduction of Earthquakes vs. Structures: Earthquakes are very important aspect of most design in civil engineering, and for any type of structure. The fundamental earthquake principles as it applies […] Read More

Structural engineering is a major branch of civil engineering, and realistically the first thing that comes to mind of many, when the words civil engineering are mentioned. It deals with designing the body of all types of structures and their supplementary components, connections, attachments per the criteria given in codes, to ensure public comfort and safety. As we mentioned in the previous post in Construct […] Read More
