Cementitious mixture and method of making the same

A cementitious mixture, comprising:

• cement with a concentration of between about 5 wt % and about 20 wt %;
• powdered glass with a concentration of between about 5 wt % and about 35 wt %;
• ground granulated blast furnace slag with a concentration of between about 20 wt % and about 40 wt %;
• sand with a concentration of between about 18 wt % and about 25 wt %;
• a poly(carboxylate ether)-based superplasticizer with a concentration of between about 0.8 wt % and about 1.2 wt %;
• and
• water with a concentration of between about 14 wt % and about 16 wt %.

A method of making a cementitious mixture, comprising the steps of:

• grinding glass to produce a powdered glass;
• mixing the powdered glass with a concentration of between about 5 wt % and about 35 wt % of the cementitious mixture, cement with a concentration of between about 5 wt % and about 20 wt % of the cementitious mixture, fly ash with a concentration of between about 20 wt % and about wt % of the cementitious mixture, and sand with a concentration of between about 18 wt % and about 25 wt % of the cementitious mixture to form a first mixture;
• adding a poly(carboxylate ether)-based superplasticizer with a concentration of between about 0.8 wt % and about 1.2 wt % of the cementitious mixture to water with a concentration of between about 14 wt % and about 16 wt % of the cementitious mixture to form a second mixture;
• and
• mixing the first mixture and the second mixture to form the cementitious mixture.
