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:Does honey contain additives?
>There are no additives added to any honey I know of. First of all, there is so much sugar in the honey that there wouldn't be any water available to dissolve chemicals into and the only thing that is really done to honey is to pasteurize it (heat treat it). Most bugs will not grow in high solids like that due to osmotic pressure, the rest are killed by pasteurization and that means no additives are needed.
Q:Fuel Additives?
it wasnt the techron that did it. i used it lots of times in my car and its fine.
Q:Vitamin C can do what kind of food additives
VC has a strong reduction, on the one hand is commonly used in food antioxidants, such as the use of VC reductive reduction of o-quinone compounds, thereby inhibiting enzymatic browning and as a modified agent for bread. But also can protect folic acid and other substances easily oxidized. It can also remove singlet oxygen, reducing oxygen and carbon as the center of free radicals, as well as its antioxidant regeneration. Commonly used in beverage production and oil and other foods susceptible to oxidation. The other is the functional food for nutritional supplements.
Q:What's the additive inverse of -3.?
Fellows, This guy is a true idiot. Don't bother answering and just report him. He's trolling.
Q:Dangers of food additives?
Dangers of Food Additives and Preservatives Although additives and preservatives are essential for food storage, they can give rise to certain health problems. They can cause different allergies and conditions such as hyperactivity and Attention Deficit Disorder in the some people who are sensitive to specific chemicals. The foods containing additives can cause asthma, hay fever and certain reactions such as rashes, vomiting, headache, tight chest, hives and worsening of eczema. Some of the known dangers of food additives and preservatives are as follows: * Benzoates can trigger the allergies such as skin rashes and asthma as well as believed to be causing brain damage. * Bromates destroy the nutrients in the foods. It can give rise to nausea and diarrhea. * Butylates are responsible for high blood cholesterol levels as well as impaired liver and kidney function. * Caffeine is a colorant and flavorant that has diuretic, stimulant properties. It can cause nervousness, heart palpitations and occasionally heart defects. * Saccharin causes toxic reactions and allergic response, affecting skin, gastrointestinal tract and heart. It may also cause tumors and bladder cancer. * Red Dye 40 is suspected to cause certain birth defects and possibly cancer. * Mono and di-glycerides can cause birth defects, genetic changes and cancer. * Caramel is a famous flavoring and coloring agent that can cause vitamin B6 deficiencies. It can cause certain genetic defects and even cancer. * Sodium chloride can lead to high blood pressure, kidney failure, stroke and heart attack. To minimize the risk of developing health problems due to food additives and preservatives, you should avoid the foods containing additives and preservatives. Before purchasing the canned food, you must check its ingredients. You should buy organic foods, which are free from artificial additives. Try to eat the freshly prepared foods as much as possible rather than processed or canned foods.
Q:Could you give me banana walnut muffin recipe without additive?
I make these muffins at least once a week cos they're so yummy they don't last long! My 2yr old helped me make this mornings batch! 3 mashed bananas 1/2 cup sugar (I use raw) 1/2 cup vegetable oil handful of choc chips (optional) (this is where u could add walnuts) 1 teaspoon vanilla essence 1 teaspoon baking powder 1 teaspoon bicarb soda 1 cup rolled oats 1 egg 1 cup wholemeal flour, sifted Combine sugar, oil, mashed banana, egg, vanilla and oats in a bowl. Let stand for 5 mins. Add flour, baking powder, bicarb soda. Stir in choc chips (walnuts). Bake in greased muffin trays, moderate oven (180C) for about 20 mins. Makes 12 medium. Yum! Enjoy!
Q:How to use food additives properly
Coloring agent (pigment): its role is to show the color of the food or dyed the color we want, the appearance is the most attractive factor, the temptation of the food appearance is easy to make consumers have seen Part of the coloring agent will have some toxicity, when the intake is too large, more than the liver load, will accumulate in the body, the kidneys, liver have some damage.
Q:Engine oil additives?
If you use a quality oil and change at recommended intervals, then additives would be a waste of money....what additive would you use that was not already included in the oil.. This is more of a concern when using cheap gas and adding fuel injector cleaners....high quality gas does not need additional additives... I would be most concerned with your cooling system, the corrosion additives deplete and must be replenished by draining and refilling with fresh 50/50 mix at least every two years...the damage to radiators, heater cores and aluminum parts of your engine can be extensive and expensive...just look on this site all the questions asked about replacement of such which could have been avoided with proper maintenance...
Q:Factory oil additives?
Additives are a thing of the past. If you want to switch to synthetic, go for it. I am sure someone will tell you not to switch to synthetic until the engine is broke-in, but this is a myth also. A lot of cars have synthetic in them right from the factory (Corvette, Porsche, Ferrari, Cadillac, etc).
Q:what is additive inverse?
The additive inverse of a number is that number which would be added to it to reach a sum of zero. It is also called the opposite, because (except in the case of zero) it has the same magnitude, but opposite sign. additive inverse of 7 = -7 additive inverse of -5 = 5 additive inverse of 0 = 0
