Q:ive been waterproofing basements for 13 years. we jackhammer concret all day and the basements get very dusty. masks are worn but their not 100%: its bad, you should be using a face mask, it can cause a disease called silicoses, and it works on your lungs over time like cement hardens. look it up.

Q:Decrease in water/cement ratio will??1)increase in strength 2)Difficult to obtain a smooth finished surface3)Decrease in strength4)Reduction in long term durability Increase in water/cement ratio will??1)Increase in strength 2)Difficult to obtain a smooth finished surface3)Decrease in strength4)Reduction in long term durability: It is sure that the strength of concrete is directly proportionate to the water cement ratio. Decrease in water cement ratio increase the strength of concrete to some extent, but an optimum ratio is to be maintened so that entire cement part of the concrete can take part in reaction, failing which the concrete will decrease its strength. More over for lesser W/C ratio the workability of the concrete will be affected. So that it is difficult to obtain finishing of your shape. on the contrary, if you increase the W/C ratio it will reduce the strength of concrete. As to react the chemical reaction of cement it required a optimum amount of water. More than that, residual quantity of water will be in the concrete structure. In due course that water will evaporate from the concrete leaving pores in the concrete surface. Which makes the concrete of lesser strength.

Q:what is type K cement?: Type-K Cement is made from materials mined from the earth and is processed using energy provided by fuels, therefore, trace amounts of naturally occurring, potentially harmful chemicals might show up during chemical analysis. For example, these products may contain up to 25% of insoluble residue, some of which may be crystalline silica. Other trace components may include potassium and sodium sulfate compounds, chromium compounds, and nickel compounds.

Q:I know it's mostly different names for the same thing, but there must be some differences. It might have something to do with adding sand and/or rocks to make a mixture, but I'm not sure.: Difference Between Mortar And Concrete

Q:How are the ashes from a volcano used to make cement?: Commercial cement is not made from volcanic ash. It is usuually made with limestone or marble (source of CaO) as the main ingredient. Other incredients include some clay and gypsum. After mixing the stuff is heated to form clinker then with some more mixing goes into bags, bins, or tanks for mixing with sand, gravel and water to make concrete. Volcanic ash will harden somewhat into a cement-like compound when it becomes wet. Many cars had their paint jobs ruined in 1980 by Mt. St. Helens ash mixed with a little precipitation.

Q:im looking to get true blue Jordan cements but i want to know were to get them, and if there is a difference? thanks to everyone! :): The only Jordans that have cement are the III's and the IV's (3's and 4's), and only the 3's have a True Blue colorway, so yes, they should be the same. Typically you can find a pair on eBay. I would also suggest staying away from other websites that sell Jordans, as most are typically fake.

Q:When installing fence posts for a 6 foot high privacy fence, I have gotten a few different inputs reference cement. Specifically, should what would you recommend and why: 1) dry pack cement into the hole and don't add water (let nature do it over time; does this jeopardize the plum of the posts initially); 2) dry pack cement into the hole and then add some water; 3) premix and then add to the hole; or 4) use quick drying cement.: I use wet concrete and a few hours later when its begun to set hose the footing with a load of water to settle the ground and make sure the cement fully swells up.. If you use wet cement you will have to brace the post until it sets if you use semi dry you can tamp it firm and hold the post fairly firm wet concrete will swell up more giving a better footing is my opinion is a good idea to put a shovel full of loose gravel into the bottom of the hole, before you pour the footing to help drainage.. if I was doing the job for myself I would use the driest pressure treated lumber possible and soak the ends that will go into the concrete in a bucket of creosote for at least 24 hours

Q:How do you make cement?: Please be clear. Do you mean how do you make concrete? or how do you make cement? If you mean how do you make concrete, get 1 part cement, 2 parts sand and 4 parts gravel, mix with water until it's a stiff workable consistancy. Wait 24 hours for concrete to become reasonably cured to continue construction.

Q:I went to Home Depot and they said there was no such thing, all cement bags have rocks, is this true? If I went to Home Depot to buy a bag, what would it say on the bag?: cement has no aggregate. there is type I type II and type N. these are usually used for brick mortar and parging of brick walls. Then you have concrete that has stone and is used for structural work such as walls, sidewalks and foundations. I used to work at a contractors supply house and at Home Depot, if the person at HD told you there was no such thing go to the Pro desk and ask them you are looking for portland cement.

Q:based on the facts that acids and bases can burn skinwhy do you suppose that people that work with BOTH dry and wet cement should be cautios: The cement is somwhat caustic (not as bad as something like sodium hydroxide, but still able to damage skin on prolonged and/or repeated contact). Both the dry powder and the mixed cement can cause problems: the powder poofs everywhere when empting cement bags and during the initial stages of mixing. It can get inhaled and get on the skin. In both cases, there is moisture present from the body to react and form the semi-caustic mixture. In the case of the already mixed cement, when laying blocks, brick or using a cement pump etc, it is almost impossible to keep from getting splattered with the wet material. Since this type of construction work is often done day after day, a relatively modest amount of skin irritation/damage each day can have cumulative effects and really get to be a problem.

Persently the company construct more than 30,000 square meter cement warehousing which can store both the large and small packing cement. The advanced technology and convenient transportation reduce the cost of transportation and storage greatly for the domestic and foreian customers. The cement product had selled to many countries,including Russia,South Africa,Angola,Nigeria,cameroun etc.
