1.Special applicator was not necessary while operating,, just need mixed repair material, sand and crushed stone with water in designed ratio, so convenient for operating.

2.This product can ensure working life more than 20mins with a higher strength. From mixing, concrete road surface resume working just need 4 hours, so it is an ideal urgent repair material for airport and expressway, etc.

3.For based on special rapid-hardening sulphoaluminate cement, this product have excellent sulfate-resisting and seawater, also can avoid the damage from alkali aggregate reaction.

4.Low rate of batch water with its slight expansion make this material have a high degree of compaction beside excellent capacity about breeze-thaw resistance and salt.

5.Excellent adhesive is to make the interface between new and old concrete firmly bond.


Using methods

1.Working surface should be a rigid and need watering before repaired, meanwhile, clear the contaminant and ponding of water.

2.According to the mix proportion of Cement based material/sand/crushed stone/water=1/1.5/1.5/0.27-0.3,and the water can be adjusted by actual demand.

3.Cement based material should be added with admixture while mixing, then feeding the mid-sand, crushed stone and water, stir for 5mins better.

4.Using in negative temperature environment, it should be use hot water and feeding turning should be according to sand first, then crushed stone and water, with the binder last. Adjustment of water temperature should be controlled well to ensure placing temperature is higher than 5°C.

5.Select the clean water accord with TGJ63 standard of concrete mixing water beside accord with the JGJ standard of medium sand and crushed stone.



1.Water, sand and stone should be neutral while they are sensitive to acid and alkali.

2.The workability should be adjusted by special admixture, it is prohibited from adding water to improved concrete performance.

3.Strength development is closely relevant to the temperature, it’s need choose suit product according to working temperature.

4.the product should be used out within working life, while prohibited mixing again for using.

5.From mixing with water within half an hour, compacting the repair concrete with a vibrator and screed surface, It is prohibited vibrating after concrete losing its fluidity.

6.While using in a low temperature environment, it should be covered and curing for a long time.

Q:cement show me how to calculate?
I do not know how you will keep it from settling but as to the volume 2 = .166 ft average height is 10' = 5/6 = .833 ft I assume a steady slope so I use average thickness 22.166 x 360.166 x .833 = 6,650.2 cu ft = 246.3 cu yds
Q:Disadvantages of using Cement help!!!!!!!!!?
Although I do not see disadvantages of using cement near lakes, because so far all dams, bridges , pillars and jetties are from concrete, unless you have some thing specific you want an answer for, please elaborate
Q:How can I stop my home entrance stairs from squeeking? It consists of wood rails with cement steps.?
cement don't squeek. I don't know what else to say. wood rails are squeeking. Why?
Q:permanent crown cement?
Don't worry it's just the cement.Sometimes it gets on the gum line and it's just flaking off.Don't chew hard things on the side that you got your crown on.It takes some time for your gumline to adjust to the crown.
Q:Should I be a Stonemason or a Cement Mason?
Not sure if this fits in Hobbies Crafts, but my impression is that a Stone Mason is a skilled profession requiring a fair amount of training to claim that title and a Cement Finisher is a far lower level common labor job - I had to do my own cement framing and finishing while redoing my garage in sections, and while I hated the work involved, I didn't encounter surprises from the information dragged from the Internet.
Q:can ticks be found on cement?
If the cement area is out of doors the answer is yes. But I would not think it would be in great numbers. Ticks live in wooded areas or grassy fields. If you have either near you they can migrate to your yard. Ticks do not jump or fly but can hitch a ride on any passing wild life. A squirrel coming through your yard can bring them in. I don't know where you are located but here in southern Illinois we havparticularlycularily bad season for both fleas and ticks. Google and read up on the proper method of removing embedded ticks.
Q:Could you make Portland cement with one component only, excluding the gypsum?
Yes. I worked before in a cement plant (at Tinaan, Naga, Cebu, Philippines). I was a shift control chemist and we fed only one component to the raw grinding process which we deposited to the slurry basin and subsequently mixed it homogeneously at the right proportions before burning in the rotary kiln to produce the clinker. Then in the finish grinding operation, we added the gypsum to control the setting time of the finished product, the cement, at approximately the proportion of 97% clinker and 3% gypsum to produce Type 1 Portland Cement. We were blessed with a very good limestone quarry that approximated almost 75% of Calcium Carbonate to crush and grind and burn to clinker and then grind it to produce cement. So almost everyday, we had only a single component to produce the cement. However, we also had in our feeders aside from the limestone, the marl feeder, the silica feeder and the pyrite cinder feeder to fine tune the raw mix, and especially when we are to produce another type of cement. A good day to you.
Q:If our new house already has tile floors, will it automatically have cement board?
nobody can venture a guess as to what the tile is set on even if there is cement board, depending on the type and how well the tile was installed there is no guarantee that it will still be reusable as an underlayment after the existing tiles are removed is it a slab home, meaning concrete floors under there or is it a wood frame house? travertine will cost about 5 dollars a square foot and up depending on size and grade just for the stone setting stone takes longer than ceramic tile and there for it costs more to install it will need to be sealed before and after grouting and occasionally for the rest of its life, higher traffic areas more often
Q:how to install cement board for tile floor?
definitely go down to the sub floor ,either use thin-set as described above or use construction sub floor glue in a tube either large or small i use it quite often and it bonds very well and is a lot quicker than thin set just make rows 8 to 10 inches apart,i recommend 1/4 inch hardy backer board ,you don't want it to be too high to match up to other floors connecting,1/2inch is used primarily on walls to match standard drywall thicknesses,mainly i use roofing nails because its a industry standard and i have a nail gun for them,but if i do it for myself and im not in a hurry stainless large head screws grab very well,you can cut the hardy backer board with a scribe and then snap it ,when im in a hurry i use a die grinder to cut its fast and easy to do curves ,bad side to that is the dust i do it out side or with a big fan in the window and aim at it ,the die grinder can be bought at harbor freight for less than 20 bucks and it also cuts tile
Q:why can't the philippine government do anything about the cement cartel?
the word cartel is not only limited to the cement industry. controlling any business operations/industry in the Phils is way too common. how's this; illegal drugs either supply, distribution and production gambling any forms rice sugar coconut hiring of overseas workers the so called smoke belching testing the so called drug testing for driver's license application you name it the Phils have it. group of people have master the art of controlling businesses apparently these cartels are HUGE fund supporters for any politicians seeking public office. Now how will this end? don't know! God save the Phils! G'Day
