I need your professional advise or opinion on a patio which I am seeing various anomalies six months after it was poured. Your input would be great appreciated. Here are the specs for the Patio. 48'x15'x 8" thick tapered to six inches on the sloped side. It supposed to be a 4000 psi concrete with fiber mesh, and 1/4" FRP rebar spaced at 24". The patio has developed numerous cracks everywhere and in every direction. I am seeing areas where the concrete is chipped off broken off and other areas where the concrete is crumbling. The control joints were cut at ten foot spands and depth of 3/8"to 1/2" max.
Increase w/c increase shrinkage: this is only happening with drying shrinkage. In autogenous shrinkage and chemical shrinkage the situation is opposite. When there is a steep decrease in internal relative humidity
literally answered my question on 0:12
why can't no one post this definition of creep smh.
Very useful videos
Confused hi dur ho gya
Glad to hear that

Dry shrinkage is after drying the concrye when loss of moisture occurs.. But plastic shrinkage is occurs after pour the concrete in plastic condition
Well explanation
Good explanation
Thanks for liking
Lov ur,effort sir
Thanks #Moon
Well explanation sir
Thanks #Narahari
Explain with image.
Top class vedio brother
Thanks alot King Usman.
If water exceed then bleeding and segregation occur not shrinkage
How do you increase the relative humidity
depends on location
wrap it in polyethylene film
Super video sir tq
Thanks #Ashok
Creep of concrete is time dependent
Q galat padha rhe ho.
Galat padhane se accha hai mat he padao.
Relative humidity increase toh Shrinkage bhi increase.
That is wrong , you show practical pic and there is no pic.
