The article mentioned above was presented at the conference IC-NOCMAT 2010, Cairo [1], dealt with the following theme: the civil construction goes to the supermarket.
Conclusions that can be extracted from this paper are: - the addition of sulfonate and sugar in Portland cement pastes can increase compression strength until 33.5%; - the addition of chalcedony and sugar in Portland cement pastes can increase compressive strength until 78.6%; - the sugar acts as a plasticizer and retarder in Portland cement; and - the combined use of additives to enhance properties of Portland cement pastes is a correct procedure and should be adopted by the civil construction.
