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: I know fuel additives like STP‘s Octane booster (don‘t complain about them I know they aren‘t all that), I know they can seriously f*ck up more modern engines. But I have a 1987 BMW. with an inline 6 engine. I am wondering if the Injector cleaner, octane boosters, etc fuel additives will damage anything.
These things are a waste of money. Octane boosters are not the same and are real. Gasoline already has additives and ethanol is known to cause problems in boat induction systems. My fear is that if you do have any varnish in your older tank that the additive might knock it off and plug the fuel filter which should have stopped anything larger than few microns from getting to your injector anyway. Fuel system cleaning at most service centers are largely an income generator with no real benefit unless they are actually cleaning the intake. Most of these shops disconnect a vacuum hose and put cleaner through it. As this path is not through the injector anyway it is of little value.
Q: Folks, I have a 1994 GCL V8 with the AWD and infamous viscous coupler just replaced both front axles and rebuilt the drive shaft, and the viscous coupler is still binding, grinding and hopping a wheel when hot on turns that are getting less and less tight. The last thing I want to do right now is replace the viscous coupler. Has any used, or is anyone aware of, an additive that would slicken things up in the transfer case and squeak a little more life out of the vc ?? Thanks in advance -
Could be the transmission - or the torque convertor.
Q: i nid it 4 mai report
natural preservatives are: sugar vinegar salt chemical preservatives: Disodium inosinate disodium guanylate others additives: salt pepper sugar hope i helped!
Q: Why don‘t smokers stand up to tobacco companies? Smoking would be a lot less harmful if it weren‘t for all the additives. I would venture out to say that a lot of smokers, indeed, enjoy smoking. they would probably continue to smoke out of their own will, with the absence of added addicting substances. Also, why do cigarette companies add lethal chems to their tobacco? What is the purpose? Would it be possible to form a smoker‘s strike? The government/FDA is not going to step in because they are in bed with the cigarette companies. Thoughts?
Sackings is right on the money.
Q: for my homework i have to find out what an additive is, please can you make it simple not dead complicated like on pedia
listen close i'll go slow an additive is something you a d d in
Q: What situation are food additives justified?
Food additives can never be justified. With our fast paced living, additives are added to many and most processed foods. Reading labels is a good idea, and try to stay away from additives
Q: math question
its the number in a set of numbers that bring a number to 0 if added or subtracted for example: the additive inverse of -10 is 10 or the AI of 41 is -41
Q: and it doesnt have a multiplicative inverse right? thanks for answering!!
Correct, additive inverse: 0 + 0 0. Correct, there is no multiplicative inverse.
Q: I love molasses.Does anything xxtra need to be done to bulk molasses bought at a feedstorre to make it as deliocious as storeshelf brands? Tuff to get this answered.
Sorry, but it is tough to get answered because most people here have no access to feed store bulk molasses. And fewer have tasted it. So I don't know. My worry would not be so much with the taste, as the safety for human consumption. I might skip this one, and not taste it.
Q: What does it mean by up to isomorphism?
That notation potential to take g(x) and positioned it in for x interior the f(x) equation. So in f(x) x + a million, i visit throw out the x and put in 2x^2 - 3 {f o g}(x) 2x^2 - 3 +a million Simplify. {f o g}(x) 2x^2 - 2
