Can you also give me the procedures, thanks.
you can buy cement mix with acrylic already mixed in at Lowe's or HomeDepot
Can cement be toughen by adding more plastics? Only if ur working on plastic cement concretes. Plastic cements on concretes can be hardened with sand on 1/2 to 1/2 ratio.
For the strongest mix use less water 5 parts powder(cement)to 1 part water.If you use more water to make it easier to use you will sacrifice strength.Yes you can add plastics but if the plastic is not ground up it may pop up when your trying to Finnish the cement.I once worked with this a- - hole i had to mix concrete for him so as he was yelling for nothing i would put cigarette butts in the mix so when he tried to Finnish it the butts would pop up making him more angry <good times>
