Concrete vs Steel

High-rise buildings dominate the skylines of our cities, and in the race to have the highest or the most modern, the boundaries of architectural engineering are pushed even further. The materials that make this possible – concrete and steel, each have their strengths and weaknesses. So, which is the better material? Safety Considerations Concrete The concrete industry has always maintained …

Properties of Reinforced Concrete

Reinforced concrete refers to concrete that has reinforcements embedded inside. These reinforcements are necessary because concrete cannot withstand tension and shear stresses encountered in the everyday operation of the structure. Environmental factors such as strong winds may cause large vibrations of a concrete structure and possible damage if it does not have reinforcement material inside. Although concrete has existed for …

Precast or Cast-in-Place Concrete Parking Structures

Most parking facilities in the U.S. are constructed using the pre-cast concrete or the cast-in-place concrete method. With escalating construction costs, parking garage owners face a difficult decision when choosing a method of construction. The method must be reasonably priced and relatively fast. These some advantages for each method. Cast-in-Place, Post-Tensioned Concrete Garages constructed using cast-in-place, post-tensioned concrete are constructed …

Advantages and Disadvantages of Reinforced Concrete

Reinforced concrete is a popular material to help ensure your structure will remain strong and durable for many years. It’s made from relatively inexpensive materials, easy to pour into shapes and it’s extremely strong. It’s lighter than it looks, about a third as dense as steel and only slightly denser than glass. Although it’s extraordinarily strong in compression ratings, it …

Construction Excavation Techniques

Constructing a building can depend on the composition of the soil, and the gradient of the site. Loose soil and steep inclines can create problems for the stability and structural integrity of a building, leading to sinking and collapse. Excavating the site is a necessary first step to ensuring the ground is level and has a uniform density before pouring …

Tremie Underwater Concrete Method

A cement tremie is a large, telescoping funnel used to precisely deposit aggregate mixtures on underwater surfaces. There are several reasons why concrete might need to be applied underwater. For example, subaqueous foundation and tunnel repair where surrounding water cannot be removed. Although there are various methods for applying concrete underwater, the tremie underwater concreting method is among the best …
