PURPOSE:To place concrete on a slope with good efficiency by a method in which concrete, etc., is poured into a flexible cylinder provided in the aperture between a formwork and a cover, and concrete, etc., is placed into the space formed by the formwork and the cover. CONSTITUTION:...
After that, the existing constitutive of unconfined concrete is studied as the foundation to establish the constitutive model for actively confined concrete, and the existing simple constitutive model for passively confined concrete is established. The two proposed constitutive models consider unconfined ...
A foundation form is pre-fabricated, shipped to job site, placed in a hole, leveled, and concrete is poured into it to form a large surface area footing topped by a pedestal having anchor bolts projecting therefrom to secure a cantilevered arm and mast, such as for traffic lights or railro...

Degradation of bond strength due to corrosion of steel strands is of great importance for serviceability of prestressed concrete structures. An analytical model is proposed to demonstrate the effect of corrosion of steel strand on reduction of bond stren
Surprisingly no cracks developed in its concrete foundation although no temperature control measures were used and over 60% of the foundation concrete was cast during the summer period with a maximum temperature differential of up to 40°C. Subsequent research revealed that the delayed expansion ...
This research is funded by the German Research Foundation (DFG) as part of the Priority Program SPP2020: ‘Cyclic deterioration of High-Performance Concrete in an experimental-virtual lab’ (Grant Numbers FI1720/7-1, GR1664/13-1, PE1464/6-1, VO829/13-1). Institutional Review Board Stateme...
Then, a refined finite element pull-out specimen model is established by ABAQUS simulation, and the numerical simulation results are compared with the real test ones, so as to make up for the deficiencies in the test and lay the foundation for further finite element analysis. Keywords: bond ...
Slope The slope of your ground also affects drainage and foundation type. Build on a slope and you may have more to excavate at one edge and need different levels of concrete blocks. If the hill is bedrock you can’t excavate, so you must rely on concrete blocks to create your level ba...
