摘要:Concrete during the curing process will appear micro-cracks inside, which will grow and be joined together to form obvious cracks due to changes in loads and environmental conditions during mining exploitation use. With crack propagation occurs abrupt fractures can occur for concrete structures. This study uses steel fibers to limit and prolong the crack resistance of concrete. Besides, to increase the strength of concrete, it is necessary to add mineral additives and plasticizers to reduce the amount of water and increase the ability to solidify the concrete. This paper uses a three-point bending test of slotted beam samples as recommended by Rilem. Rilem method uses a crack control device, here the team uses a CMOD device manufactured by Controls.
