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:Please answer ASAP!: For every real number, is there a number that you can add to it to get zero? For example, say the real number is 2. Add -2, and what do you get?

Q:Find the additive inverse (opposite) of:18/23?: Additive inverse of a number is a number which when added to the given number gives a total of 0. So the additive inverse is -18/23

Q:How to do pesticide residues every day and food additives: When we pack, dilute and spray pesticides, they will accidentally stick the pesticide in the hands, face and other skin parts exposed to the outside of the clothes. After the skin is contaminated with pesticides, then the pesticide is adsorbed, and then penetrate into the body, the formation of acute exposure. Different pesticides have different penetrating ability to the skin. Some pesticides are liquid and contain some organic solvents that are easier and faster to penetrate into the skin than solid-phase pesticides and water-based pesticides. If the skin is contaminated with many pesticides, in certain circumstances, in a few minutes to produce adverse health consequences. Once the pesticide into the dermis, reaching the skin of the capillaries, will soon enter the blood. Pesticides, even if only stay in the skin parts can also cause dermatitis, including irritating dermatitis and allergic dermatitis

Q:How are Hormones, Additives & Stimulants help to get plants growing? ?: not really other than oil or fuel leaking out

Q:chemistry: The E-number system was originally used in the European Union in order to regulate the use of substances added to processed foods and drinks to colour them, flavour them, change their texture or enhance their keeping qualities. Additives were given a unique number and those which were approved for use were prefixed by 'E'. (1) Additives are numbered according to their main purpose as shown below: E100 - E199 (colours) E200 - E299 (preservatives) E300 - E399 (antioxidants, acidity regulators) E400 - E499 (thickeners, stabilizers, emulsifiers) E500 - E599 (acidity regulators, anti-caking agents) E600 - E699 (flavour enhancers) E900 - E999 (miscellaneous) E1000 - E1999 (additional chemicals)

Q:Antioxidant TBHQ is a generic name for food additives in national standards?: (TBHQ) I think we can, 1 in GB2760-2017 embodied, 2GB7718-2017 allowed table INS code, but did not say that the table can be abbreviated, but the actual bid BHA, BHT abound, And we all understand

Q:Safe to consume chemicals that counteract additives in food?: There are about a million food additives, including unintentional additives, so specific chemicals would be needed to counteract each of these many additives, most of which would be of doubtful safety. Example: Salt substitute potassium chloride, can help our body deal with excess salt, but too much potassium chloride is also bad. Neil

Q:a. x+0=xb. x+1=1+xc x+1+(-1)=xd (x)(1/x)=1i think its C. because its the best that fits, but can u kinda explain: A is the Additive Identity (you can add 0 to anything to get the same number back) B is the Commutative Property (you can add or multiply in any order) C I guess this would be the additive inverse because you are adding a number and then adding the negative of that number (which is what subtraction really is). D is the Multiplicative Identity (if you multiply something by its reciprocal you get 1)

Q:Explain why every integer has an additive inverse. Then identify the integer that its own additive inverse.?: So 1 and -1 are their own multiplicative inverse.

Q:Is it really true that Additives & stimulants help for quality growing? ?: It depends what they are, and whether your plants are growing near to their optimum level. Overall, if your plants are getting high quiality nutrition and good levels of lighting, then you'll get good quality productive plants. There are 'miracle' cures out there, but much of it is hype and, in my opinion, prays on the grower who is not a horticultural scientist. Overall, if you can apply organic grade additives then you'll not affect the ability of your plants to be nutritious and fulfilling etc. This also depends on how you're growing, as soil based growth is likely to provide most nutrients that plants want, hydroponically grown produce should have its input tailored to what you're growing, as well as its position in the growth cycle. I recommend researching the individual plant types that you're growing - some have greater difficulty with the uptake and utilisation of certain nutrients, but these are the rarity, and not the norm. Plants naturally contain hormones etc, and can usually produce them in sufficient quantity to manage their growth, flowering and seed production. If you've got products in mind, compare similar products as it's easy to pay too much for roughly the same stuff. That's if you really need it, of course. Edit your question if you've got any specifics, otherwise feel free to message me for any other advice. Hope this helps. Good luck! Rob
