I have a project I'm got roped into. Pour a slab and apply an epoxy chip floor on it in 7 days. I leaned on my concrete supplier and he came up with a mix design. 6 bag mix with a high range water reducer and 15% micro silica additive. Well I poured this "fun" little piece of concrete at a 4" slump and had 4 guys there to handle a 400 sq. ft. slab and it worked our butts off especially mine since I'm recovering from a major ham string(s) rupture. I installed a 15 mil vapor barrier under this slab and taped it closed real well.
This mix is very interesting. It is gaining popularity with the high performance concrete installation crowd. The mix is to have reduced dry shrinkage, a real low permeability with suppressed alkali and silica reactions. I applied my vapor emissions test kit today and will be doing a rapid RH test on it the first of the week. pH levels were at 9.5 today.
There have been epoxy applications applied on 9 days old slabs with success...... I'm hoping this will turn out well. I'm taking pics and will put them together when done. gene(hoping the vb5 does the trick) ec-Indy
