Claim 0:
1. A process for the preparation of a concrete mixture in a Ready-mix, said process comprising the steps of:
A) creating a concrete mix from components in the Ready-mix, said components comprising each of the following:
a) a quantity of dry cement mix, said cement mix characterized by one of:
i) a manufacturer suggested water/cement ratio value; wherein said suggested ratio value falls in the range of from about 0.35 to about 0.65; and whereupon in combination with b), the water/cement ratio is not greater than the value corresponding to about 30% greater than the suggested value;

or
ii) a manufacturer suggested water/cement ratio range, the manufacturer suggested water/cement ratio range having an upper value and a lower value, and whereupon combination with b) below, the actual water/cement ratio is less than about 30% greater than the upper value;
b) a quantity of water;

c) a quantity of amorphous silica, wherein the average particle size of the amorphous silica is in the range of from about 1 to about 55 nanometers and/or wherein the surface area of the particles of the amorphous silica is in the range of from about 300 to about 900 m2/g;
d) a quantity of aggregate and/or sand; and
B) wherein the water of b) is added in its entirety or in portions comprising an initial portion, consisting of at least about 20 wt % of the quantity of water, and a tailwater portion; wherein the initial portion of water is combined with a) and the components of d) to form a first mix; and
wherein the amorphous silica is added to the first mix to form a second mix;
AND
wherein the tailwater is 1) added to the first mix or 2) added to the second mix; or 3) is co-added with the amorphous silica to the first mix, wherein the amorphous silica and the tailwater are, optionally, intercombined; and wherein 1) the first mix is agitated for a time prior to the addition of the tailwater, for a time after the addition of the tailwater but before the addition of the amorphous silica, and for a time after the addition of the amorphous silica; or 2) the first mix is agitated for a time prior to the addition of the amorphous silica, for a time after the addition of the amorphous silica but before the addition of the tailwater, and for a time after the addition of the tailwater; or 3) the first mix is agitated for a time prior to co-addition of the amorphous silica and the tailwater, and whereupon the concrete mix is then agitated for a time;
OR

C) wherein the quantity of water of b) is added to a) and the components of d) to form a first mix, agitating the first mix for a first time, adding the amorphous silica of c) and adding a tailwater portion comprising the remainder of the quantity of water of b), if any, to the first mix to form a second mix, and agitating the second mix for a second time.
