Through the use of new or innovative technologies, the goal of PATH is to improve the quality, durability, environmental efficiency, and affordability of tomorrow's homes. PATH, initiated jointly by ...
متن کاملThe Development of Self-Propelled Machines in Illinois for Construction of Concrete Slabs Without Forms
There have been many important developments in road building equipment in recent years; possibly the greatest progress has been made with earth-moving equipment. The size and mobility of earthmoving equipment have been developed to such an extent that pro duction has been increased tremendously on the average road con struction project. This has had a definite effect on the cost of road work ...
متن کاملConcrete Shear Wall Construction
Buildings with cast-in-situ reinforced concrete shear walls are widespread in many earthquake-prone countries and regions, such as Canada, Chile, Romania, Turkey, Colombia, the republics of the former Soviet Union, etc. This type of construction has been practiced since the 960s in urban regions for mediumto high-rise buildings (4 to 35 stories high). Shear wall buildings are usually regular in...
متن کاملCrack Resistant Concrete Material for Transportation Construction
Most transportation infrastructures are exposed to a combination of mechanical and environmental loads. Normal concrete is brittle and tends to crack, resulting in a lack of durability and frequent repair needs. This paper describes an ultra ductile cementitious composite which is highly crack resistant, with a tensile strain capacity over three hundred times that of normal concrete. Apart from...
متن کاملUse of Polymer Concrete in Construction
Polymer concrete (PC) is a composite material in which the binder consists entirely of a synthetic organic polymer. It is variously known as synthetic resin concrete, plastic resin concrete or simply resin concrete. Because the use of a polymer instead of Portland cement represents a substantial increase in cost, polymers should be used only in applications in which the higher cost can be justi...
