Q:When doing a Science project about friction on bouncing a ball on cement and carpet. If I Start with?
Your independent variable is the thing that changes, which is the surface the ball is bounced on (like cement or carpet, but not just one of those) Your dependent variable is the variable that is effected by the independent variable, so the height that the ball bounces. Your controlled variable is the thing that does not change, the constant, so that would be your ball. Tips: for a good experiment, you should have more than 2 things in the the independent variable, so you should try other surfaces as well such as wood. Also, to avoid any error, buy multiple of the same ball and use each one on a different surface. That way the cement won't scratch the ball and cause friction between the ball and the carpet, but the balls will have the same bounce so it won't change the height.
Q:how to estimate the # of bags of cement, sand & gravel...?
There are a couple of rules of thumb for determining quantities required for a project. The old rule is a ratio of 1:3:4 Cement to Fine Aggregate (sand) to Coarse Aggregate. But this describes the mix proportions and since the cement and fine aggregate will disappear into the voids in the coarse aggregate another ratio is recommended. A common approach is by the bag mix ratio. A 6 or 7 bag mix will be quoted. These are ratios of numbers of regular bags of cement per cubic yard of mix. A 6 bag mix will normally require 6 bags of cement 15 cubic feet of fine aggregate and 20 cubic feet of coarse aggregate. A 7 bag mix will require 15 cubic feet of fine and 21 cubic feet of coarse aggregate. Why don't they add up to 27? Welcome to the wonderful world of concrete.
Q:What is significant is Cement PSI (Its power Strength)?
First of all, cement is not concrete and you are referring to concrete which is a mixture of cement, water, and a mix of aggregates. The higher strength concrete of 8500 psi is best used for concrete columns where high axial loads are present. 5000 psi can be used for elevated beams and elevated slabs. Foundations are typically 3000-4000 psi only. With higher strengths mixes, the water-cement ratio is critical. In my job as a structural engineer, I mostly deal with 3000-4500 psi. The strength of the concrete mix is completely independent of the unit weight of concrete. Concrete is assumed to weight 150 lbs/cubic foot regardless of its strength.
Q:Permanent Retainer Glue/Cement?
Whether or not it comes off is dependent on two things, really: 1: you not eating dumb things, like gum or air heads, etc. and 2: your bite. Some just do. The glue will stay as long as the bond took. Some may chip off from your bite, but there's not a lot you can do aside from being careful to stay away from foods that you are not supposed to eat. The glue can last years and years. It's the same stuff we use to cement crowns and it lasts decades. But adults don't do the same dumb stuff with their mouths that kids do.
Q:How do i remove cement board from the top of ceramic tile?
Q:Has anyone used a cement tile to?
I agree with Fraz. I would use sand mix.(just add water) Use thin-set to glue tiles to wall and I would also back butter each tile before placing them. Good Luck
Q:Is it possible to use regular rubber-cement to work on inner-tube bicycle tire? There is a small rubber-?
Regular Fries
Q:My dog swallowed rubber cement!?
Take it to a emergency hospital. Yes, rubber cement being swallowed would be harmful to both humans or other mammals. I suggest you first call a vet to make sure, and then do as they instruct, even if it would be just as the following said take it to the emergency hospital. I suggest calling the vet first, just in case.
Q:rubber cement on walls?
There are actually packages of little sticky balls (grey, consistency of gum) that you can use. The schools all use it to put posters up on their walls. It's the same stuff that comes with the glow-in-the-dark stars and planets that some kids put on their ceilings...
Q:Can someone tell me where to buy White Portland Cement?
In the 1820s, Aspdin’s quest for a manufactured counterpart to natural or Roman cement (derived from volcanic ash and other naturally occurring minerals) led to his discovery and patent of portland cement. Aspdin’s name for his invention served two purposes. It distinguished the material from Roman cement, which existed for centuries. It also was a marketing ploy. Concrete made from his new cement resembled a highly prized building stone quarried on the Isle of Portland.
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.
