2020-7-7Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement cement paste that hardens cures over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete named for its visual.
Of concrete piles were devised. These early concrete piles were the cast-in-place type. Further development of the concrete pile led to the precast pile and, relatively recently, to the prestressed concrete pile. The need for extremely long piles with high bearing capacity led to the use of concrete-filled steel-pipe piles about 50 to 60 years ago.
The main benefit of secondary aggregate is its low cost on average, it is two times cheaper than the granite type. Power input for its production in comparison to other types of aggregates can be up to 8 times lower. The prime cost of concrete in which secondary aggregate is used as a large filler is a quarter lower. sand, river gravel.
