1.Remarkable Plasticity: As a condition of blending where amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by 17-25% when it is admixed with reinforced concrete at 0.5-1.0%. Statistically, compression strength on the lst day, the 3 rd day and the 28 th day after single application is increased by 60-95% and 25-50% respectively when it is added at standard blend dosage. As a result, compression strength, tensile strength, buckling strength and modulus of elasticity will be improved to some extent.
2. Improve miscibility of concrete amalgamator with water and collapsibility as well. As a condition of equivalent blending, collapsibility can be increased 4-7 times when it is added at 0.7% blend dosage.
3. 15-18% of cement can be reserved when the agent is blended at 0.7% blend dosage, which is preconditioned by same collapsibility and strength.

Q:Chicken powder is not a food additive: Chicken powder is not a food additive, it is a seasoning, just like the presence of soy sauce, salt and so on.

Q:1) 0.42) -1.63) - 11/164) 5 and 5/6: 1) 0.4 Additive inverse -0.4 Multiplicative inverse 1/0.4 2.5 2) -1.6 Additive inverse 1.6 Multiplicative inverse 1/(-1.6) -0.625 3) -11/16 Additive inverse 11/16 Multiplicative inverse -16/11 4) 5 and 5/6 Since 5 and 5/6 35/6: Additive inverse -35/6 Multiplicative inverse 6/35 .

Q:Brother I would like to get some antifreeze that big brother know how to provide point clue ratio Thank you pull: Ethylene glycol 940.15%. Borax 3%. Sodium silicate 1%. Potassium nitrate 0.25%. Sodium nitrite 0.15% Trinitrophenol

Q:Helping lubricate valves, high mileage engines, increasing compression.all of the claims on the labels, are they true? Better yet, are they worth the money?: I'm not a big fan of any oil additives, just my opinion, of course. The only additive that I will ever use is Lucas, I have had good luck with all of there additives.

Q:How can we prove that the additive inverse -u is unique of a vector space?: whenever your not sure you can iron something, iron on the lowest power on the corner of the shirt

Q:Does the feed additive report the same as the veterinary drug?: New feed and new feed additives management approach requires the need to verify the other feed additives:

Q:a. [ 1 1 1 1 ] [ 1 1 1 1 ]b. [ -1 -1 -1 -1 ] [ -1 -1 -1 -1 ] c. [ 0 0 0 0 ] [ 0 0 0 0 ] d. [ 1 1 1 1 ] [ 0 0 0 0 ]: The additive identity is the matrix that you can add to any matrix without changing it. in the 2x4 case every entry is 0. so C

Q:state the meaning of the word additives by using word parts?: Additive comes from the Latin additivus or additio, from the past participle addere, and meaning added or additional.

Q:i need this asap! thnx in advance!!!: The additive inverse is the number you add to total 0 It is therefore 8 + 5i

Q:How can we prove that the additive inverse -u is unique in a vector space?: Let u be an arbitrary vector from some vector space. By the axioms of a vector space an additive inverse of u must exist. Suppose v and w are both additive inverses of u. By definition this implies: u + v 0 and u + w 0 u + v u + w [equivalence] v w [add (any) inverse u to both sides] Since v and w may be any possible choice of available inverse u's, all inverse u's are identical. i.e. the additive inverse of u is unique.
