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: Thanks for the replys: I don't know of an easy way to remember the tube types and tests. Its just something you have to work on - though it does come pretty quickly. Another important item is the draw order of the tubes. It's very important to ensure that tube contents don't contaminate subsequent tubes and cause erroneous results.

Q: IS THERE ANY MARKETED ADDITIVE THAT COULD CLEAN UP OR DO ANYTHING TO PRVENT A ENGINE LIGHT FROM COMING ON: No. Go to autozone, have them read out the trouble codes for you. Fix the problem. The code usually points you in the right direction, most often a failed sensor. Disconnecting the battery and reconnecting it will not clear the memory. Fixing the problem will generally turn off the light, although it may take a number of driving cycles before the stored data is overwritten.

Q: Additive action and mechanism: Oily agent boundary lubrication mechanism and the role of adsorption film

Q: give you a significant increase on mpg. . have you or anyone you know tried these, and if so were the results good: Well, if you read the fuel additives carefully and follow the instructions carefully and do everything they say, you will get an increase. But you would have got that increase without the additive.just do all the other steps. Cleaning your intake valveswhat does the engine know about clean(or dirty) intake valves? Nothing. It just runs. And in order to have that kind of build up you need to have been putting in low grade gasoline for 10 years with alot of idling and slow speed driving such as farm trucks on the farm to get that kind of build up. The engine still ran fine. Build up? Yeah.had to grind it off the valves. No gas would ever get it off in a couple of tankfuls. So additives are just a drain on the pocket book, but do help(instructionwize) if you drive as they dictate.

Q: i have my alg. final in 03 days!! help me plz!! when do you use additive inverse!!!: The -ve of the number is called additive inverse. 3 and -3 are additive inverses of each other.

Q: ive seen a lot of fuel treatment additives on the shelfs.I want to know what is a good one to use on a chevy 350! i know i have to use the ones for carbs and i know quite a bit about fuel additives, but i want to know which is the best one for a chevy 350. I want to keep the build up off of my pistons and values, to keep the engine running smooth. It runs good right now, but i want to keep it that way! please give me some names and if possible, prices! Thanks a lot-): Good question, the best fuel additive on the market and has been for nearly 70 years is Marvel Mystery Oil fuel additiveget it at any auto parts store for about $3.50 roughly a bottlethoroughly cleans fuel injectors, valves, fuel system and removes water and impurities from your gasolinewill keep your car/truck idling smoothI have been using it since 1961.(Marvel has been in business since the 1940s)******

Q: can some one help me its for a science project list both and make a balence: Pros: Grown without pesticides, synthetic chemicals, preservatives, non-irradiated, non-genetically modified, better nutrition for the person ingesting them, less toxicity for the person ingesting them, feeling of better well being is markedly noticeable Cons: Expensive, shorter shelf life ,limited availability, limited selection If you hear news reports telling you that there is no difference between the two, consider the source : It's just like most western medicine doctors telling people that vitamin supplements don't help people. Of course they are going to say that. Doctors want you to be sick so you'll buy their pimp's (pharmaceutical companies) drugs and spend money on doctor visits. Also pharmaceutical companies and most western medicine doctors don't make any money off of vitamin supplements or the fact that you are healthy.. Something to think about, huh? Believe it... cause it's true. It's a sad state of affairs, but it's definitely true

Q: My Honda Civic 2003 burns oil What kind of oil should I use? should I use an additive as well?: In a way the Union did demand ridiculous request, but only because they knew they were up against weak management. The union leaders were there for the long run. But the biggest change came starting in the 1970 when corporate America decided to keep new blood and fresh ideas flowing by constantly changing upper management and from promoting from outside. Now the management team that makes a decision knew they would not be around when it came time to pay the piper for their dance. Upper management used to be grown right in the company. Today all HR want to know is if you have a college degree and no longer cares about experience. So if you know you are worth $15 per hour but can get $25 for the same work, what would you do? ???

Q: What is the additive?: Wang Zi milk is to restore the milk, that is, milk powder and then processed to produce milk. Additives, there will be some ordinary milk, after all, is a packaged food, there will be a small amount, I think Wang Zi milk inside may be more than ordinary milk, and if not the original flavor, and may add more, but these additives Are relatively safe, basically there will be other food inside, so do not worry too much

Q: Can you make the chicken grow up with no additives: Hello, first with a lot of foam soak after curing fried, chicken products bulky full. OKorder sell small package bubble source, you can buy less try.
