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:What are the food additives in ice cream?
China Agricultural University nutrition and food safety department director He Jianguo introduction, whether it is -22 ℃ or -18 ℃, home refrigerators are difficult to achieve for a long time. Ice cream in the professional cryopreservation of the total number of viable is generally not increased, but the freezing can not be completely sterilized, and the minimum temperature of the refrigerator with the family can only reach -18 ℃, coupled with frequent switch refrigerator door, so simply not reach the manufacturers Strict storage requirements, will affect the taste of ice cream, so that the protein degeneration, the quality of the affected, so the best cold drinks in the refrigerator within a week to eat finished. In particular, note that the ice cream is easy to breed after melting bacteria, so melted can not be put back to the refrigerator.
Q:what is food additive ?
Q:What are the benefits of food additives to us?
Food additives are synthetic or natural substances that are added to food in order to improve the quality of food, aroma and taste, as well as the need for preserving and processing processes.
Q:additive and multiplicative inverse?
Definition Of Additive Inverse
Q:Additive function a: R → R is an increasing function .it is continus.why?
Any additive increasing function α: R → R is linear of the form α(x) = α(1)x, hence is continuous. Proof. Suppose that (1) α(x + y) = α(x) + α(y), for any x, y in R, and (2) α(x) ≤ α(y), for any x, y in R, x ≤ y. Applying (1) we have: α(0) = α(0+0) = α(0)+α(0) ==> α(0) = 0 0 = α(0) = α(x+(–x)) = α(x) + α(–x) ==> α(–x) = – α(x), for any x in R α(x – y) = α(x + (–y)) = α(x) + α(–y) = α(x) – α(y), for any x, y in R If n is a positive integer then, for any x in R α(nx) = α(x+x+...+x) = α(x)+α(x)+...+α(x) = nα(x) If n is a positive integer then, for any x in R α(x) = α(n(x/n)) = nα(x/n) ==> α(x/n) = (1/n)α(x) If m, n are positive integers then, for any x in R α((n/m)x) = α(n(x/m)) = nα(x/m) = n((1/m)α(x)) = (n/m)α(x) Collecting the previous results, we have α(qx) = qα(x), for any x in R, q in Q In particular, α(q) = α(1)q, for any q in Q Next I apply (2) to show that α(x) = α(1)x, for any x in R. Fix x in R. Since Q is dense in R, given ε > 0 there are p, q in Q such that p < x < q an q–p < ε. Then α(1)p = α(p) ≤ α(x) ≤ α(q) = α(1)q, so –α(1)(x–p) ≤ α(x) – α(1)x ≤ α(1)(q–x) –|α(1)|ε ≤ α(x) – α(1)x ≤ |α(1)|ε The previous inequality holds for any ε > 0, hence α(x) – α(1)x = 0 bye
Q:What food additives are used to achieve crisp package line
Hello, this is more, the key to see what you do food, food additives have a range of use, the more useful bulky crisp agents are: face Xin crisp, Shu Xin crisp, beans Xin cakes and so on.
Q:Whether the cake oil belongs to the government prohibits the use of food additives
No, cake oil is allowed by the state, mainly used in sea cakes. Is a less toxic, relatively safe food additives. In the "National Food Additive Food Hygiene Standard (GB2760)", the use of such additives are clearly defined, the general maximum use of 6g / kg.
Q:Qinghai Xining City where to sell food additives
Generally in each city there are some concentrated baking raw materials wholesale and retail market or the whole street.
Q:Is pepper a food additive?
Does not belong to additives, are natural spices.
Q:Where is there a place to sell food additives in OKorder?
To the new wholesale market, in the South Fifth Ring. There are a lot of additives stores, are relatively small. If you go to large, it is recommended to Xiaguang supermarket. You can ask the phone by 114, they have shops do wholesale, the variety is still full technical support.
