I. Product Overview

Cement is used as basic material in cement-based Grouting Material, which is dry mixture made by cement together with appropriate natural high-strength aggregate, a variety of concrete admixtures and other components. It has high liquidity, early strength, high-strength and non-shrink characteristics after mixing with water. It is widely used in equipment foundations, steel base, secondary grouting and bolts anchoring works, as well as concrete beams, columns, plates, wall reinforcement, concrete hollow supplemental and irrigation repair, etc.

II. The technical performance

Products are divided into common type, high-strength type, early strength type, anti-freezing type, high-flow type, in which ordinary and high strength types fulfilled the JC/T986-2005 standard, the early strength and grouting agent types are fulfilled the New Zhongyan standard. Product technical indicators are as follows:

III. The main features

▓Good fluidity, no bleeding, it can automatically fill to the required grouting gaps;

▓It has early strength, high-strength performance. It can improve the impact resistance and vibration resistance as equipments operating. Different types of UGM can meet different requirements of projects.

▓ It has the characters of high bond strength, no shrinkage and micro-expansion that can ensure the solid combination of anchor bolts and base, as well as the old and new concrete.

▓ It has good crack resistance and impermeability, impermeability grade is higher than P20.The excellent no-shrinkage performance to ensure there is no cracks in the large area construction.

▓The type with early strength has performance of anti-corrosion. It has good performance of sulfate resistance and anti-sewage corrosion. Its erosion resistance performance can be used in harbor, sewage treatment plants and other projects.

▓UGM belongs to inorganic grouting material and it has good durability, so it is no aging, no corrosion to steel. Due to its low alkali content, it can effectively prevent harmful alkali-aggregate reaction.

▓The powder bulk density is 2100 to 2400kg / m ³ .

IV. Method for use

See YB/B9261-98 “Cement-based Grouting Material Technical Specification for Construction”

◆Construction preparation:

Before constructing, dust and loose materials on the surface of filled space should be cleaned up, the oil should be removed. The concrete surface of filled space should be pre-wetted at least 6 to 12 hours with clean water.

◆ The amount of adding water:

Water can be added directly. For ordinary type, the mixing amount of water is 13% to 15% of grouting material.

◆Method for mixing:

Grouting material can be mixed with mixer or by hands till homogeneous. When the construction temperature is high, more water is added to get the required fluidity.

◆Method for grouting:

It should be grouted continuously without stopping, and shorten the filling time as much as possible. Vibrating is prohibited as grouting. If necessary, pulling diversion with bamboo sheet. Grouting to dense and slightly dry, the outer surface is cleaned smoothly. There are three common grouting methods, showing as below.

1. Self-gravitation Method Grouting

2.High-place Funnel Method Grouting

3.Pressured Method Grouting

V. Notes

The amount of water can not be too much to cause bleeding and segregation of the slurry. Once the bag is opened, use it up as soon as possible.

VI. Package and storage

Plastic woven bag, net weight is 25 kg / bag and 50 kg / bag, valid period is one year. It should be stored in dry and ventilated room, pay attention to moisture-proof.

VII. Applications

Application in the Water Cube Olympic Swimming Pool steel base

Application in High-speed Railway Bridge bearing

Application in the cement plant equipment foundations

Application in the installation of wind power

Q:Hasn‘t been rebuilt. Old 289 from 66 mustang. I‘m talking about how fuel in the 69s had lead which I think protected the valves but now with unleaded gas I heard that it could ruin the head.: needs hardened valve seats to run on the unleaded crappy corn gas we have now

Q:Sketch a proof that every complex number has an additive inverse?: Your atv has its own hamlet? Fancy

Q:Assuming the volumes are additive, what is the [Cl-] in a solution obtained by mixing 240ml of 0.635M KCl and 640ml of 0.380M MgCl2 ?: Mol KCl in 240mL of 0.635M solution 240/1000*0.635 0.1524 mol KCl KCl dissociates: KCl ? K+ + Cl- Therefore you have 0.1524 mol Cl- ions Mol MgCl2 in 640mL of 0.380M solution 640/1000*0.380 0.2432 mol MgCl2 MgCl2 dissociates : MgCl2 ? Mg 2+ + 2Cl- Therefore you have 0.2432*2 0.4864 mol Cl- Total mol Cl- 0.1524 + 0.4864 0.6388 mol Total volume 240+640 880mL 0.880L Molarity 0.6388/0.880 0.726 M solution of Cl- ions.

Q:We added dry gas to the tank after filling up the tank with bad gas. It is running better ( not stalling and hesitating), but not perfect. It is a 2005 Highlander with 55,000 miles, that we have never had a problem with before this. Would an additive for the fuel injector help?: If the gas is contaminated with water, gas-drying additives may help. If it is old gasoline, use a product called sta-bil to refresh the fuel. Other contaminates may require draining the gas tank. A quality injector cleaner would help, and dillute the bad gas with fresh, good gasoline by refilling your tank as soon and often as you can. Many fuel additives contain high percentages of alcohol. Be careful not to overdo the fuel treatment, it may do more harm than benefit. Good luck with it.

Q:lucas oil additive?: Lisa, As a last resort. I used Lucas transmission additive and it fixed a slight shifting problem. I am still driving that car with lucas in the tranny. The additive was a last resort, as I had a replacement. If I did use an oil additive, I would add it, run 1000 miles, do an oil change. Use factory recommended oil grade and see if that makes a difference

Q:There is a lot of additives that think of the taste (open cup) instant noodles. What will it eat? Has been eating for two days (morning).: Additives such things, really harmful to the human body. But you only eat two cups of instant noodles will not hurt what the body, this additive is after a long long into the human body may find toxic. The amount of additives will not soon cause discomfort, after all, you have to excrete, toxic substances will be discharged with the body, as row row row less, to see how your metabolism. If you think a lot of additives, to stop using it, and now the food is not good to say it, after all, there are preservatives instant noodles ... ...

Q:additives ,have you tried these products?: You use 2 quarts of stabilizer to 1 of oil? As thick as that stuff is, it's a wonder the motor will crank. I wouldn't go above a pint per 4 quarts of oil.

Q:I have heard of the stuff called Sentek. Does it really work? How will i know?: Tetra-ethyl lead is the answer to your question as the best fuel additive - unfortunately, it's extremely toxic and we have to compromise the octane rating with aromatic hydrocarbons, ethers and alcohol (usually ethanol or methanol).

Q:What kind of milk contains more additives, 2% or whole?: If by additives you mean the crap they give the cows to make more milk, then both. It is best to go organic or soy to avoid said additives. I was raise on a dairy farm and we never gave our cattle antibiotics and what not? to make them produce more milk. We fed them, loved them, and never over milked them. They had hundred of acres to graze on and we didn't eat themlol Stay away from generic milks (ie store brands). Also it is best to buy milk in cartons since the plastic containers can contaminate the milk with cancer causing chemicals. If I sound a little nuts over this,well I am. We have too many female cancers linked to milk and other cancers as well.

Q:What are the additives 50 for cooked food?: Most add preservatives, pigments, nitrites, industrial bases
