1. mid-range water reducing admixture
2.hydration controlling admixture
3. viscosity modifier admixture
which has better effect on porous concrete
obviously strength should be increase but not at the cost of permeability!
porous concrete is used to permit water to penetrate in the land and reducing storm water.
Hi Mr Ashish Guruji
water reducer or superplasticizer will result in higher strength in production of porous concrete. also its cost share for the final product will be minimum. If you need more strength, the synthetic polypropylene fiber can be the best solution.

Hi,
Porous concrete, It is usually an intermediate layer material, so its strength is not really important. Probably you need other special characteristics, porosity, permeabillity, etc.

Hi
What porous concrete do you mind? Autoclaved aereted concrete ?Autoclaved aerated concrete (AAC) is known as autoclaved cellular concrete (ACC), autoclaved lightweight concrete (ALC), autoclaved concrete, cellular concrete, porous concrete.

you may use super plasiticizer with porous concrete ,foamed concrete for example, but with care in mixes with low densities (1000 Kg\m3 and below) as there may be a chance for segregation or bleeding occur. of course using SP also will be useful for strength increase without affecting bubble system of the concrete in use.
anush,
thank you,
but as per my perception and scholars around me, suggested me that ,flyash will not serve purpose,because it will choke the perviousness of concrete,
I also agree with them,for making pervious concrete flyash not work.
