That big damn slab of concrete is quickly gonna crack. Nothing about this is modern technology technique. Also, road is supposed to be from robber and rock, NOT concrete
콘크리트 믹서 트럭: - 콘크리트는 신속하게 운반하여 즉시 치고, 충분히 다져야 한다. 비비기로부터 치기가 끝날 때까지의 시간은 원칙적으로 기온이 25도를 넘었을 때는 1.5시간을, 25도 이하일 때는 2시간을 넘어서는 안된다. - 콘크리트 믹서 안에는 시멘트, 물, 자갈, 모래 등이 혼합되어 회전하고 있다. - 믹서 트럭의 믹서가 회전하는 이유는 골재, 시멘트 및 물을 완전히 혼합하여 균질한 혼합물을 생성하고 운반 중 재료 분리가 발생하지 않게 하면서 동시에 양생을 방지하기 위해서이다.
Reinforced concrete pavement is rare. It's only for highways with extreme truck traffic, or where frequent truck turning is prevelant. Most highways that are concrete are non reinforced but have dowels at the joints.
Who in the world dumps 3 loads before they start to strike off. And the guy on the vibrascreed isn’t even using a wet screed, wtf are these guys doing?
That "road" would last for about one year here, no reinforcement, water content of the concrete is much to high unless they are using a P or super P. Any decent sized load on this road would crack it to hell and then more would turn it into dust. There are higher standards here for driveways.
News flash!!! Steel reinforcement does not stop concrete from cracking!! Also there was nothing wrong with pouring at a 4 inch slump!!! This driveway will outlast you!!
this concrete road work is failed in inspections, they didn't use one of the most important machine which is the mechanical vibrator to consolidate the concrete and to bring out air pockets in the concrete poured. maybe steel dowels are not required on plans because the whole width of road pavement was poured one time. mechanical screed to finish the concrete can save time.
Javier Leon, i watched again part of the video and you are correct this is one type of surface vibrator which is the vibrating screed it is the single beam vibrator. i don't know if the volume of entrapped air which is about the in range of 5 to 20% are eliminated especially below the poured concrete. good consolidation is the key for better concrete.
