The slurry infiltrated fiber concrete (SIFCON) is nowadays considered a special type of high content concrete; it strength and performance material. This paper investigates the effect spread steel into mortar on some properties SIFCON. According to distribution, two sets were used in this investigation. first set consisted randomly distributing fibers inside slurry. second was by placing an ord...

There is no doubt that concrete one of the most consumed materials all over world. It a composite mix widely used for constructing structures and infrastructures to sustain environmentally induced stresses such as thermal seismic. As mainstream construction industry tended find out feasible solutions, Roller Compacted Concrete (RCC) was introduced play an essential role in development dams pave...

BACKGROUND The objective was to investigate the effect of placing mats on concrete slatted floors on performance, behaviour, hoof condition, dirt scores, physiological and immunological variables of beef steers, and to compare responses with animals on out-wintering pads. Continental crossbred beef steers [n = 360; mean (±SD) initial live weight 539 kg (42.2)] were blocked by breed and live wei...

background: in megavoltage radiotherapy rooms, ordinary concrete is usually used due to its low construction costs, although higher density concrete are sometimes used, as well. the use of high-density concrete decreases the required thickness of the concrete barrier hence, its disadvantage is its high cost. in a nuclear reactor, neutron radiation is the most difficult to shield. a method for p...
