Q:how to break a cement wall with fist?
Take a running start, 50 feet back from wall, run as fast as you can, hold your arm straight and stiff at less than 25 feet, make a fist with your hand at 20 feet or less, at 10 feet or less think of why are you doing this, close your eyes at 5 feet, and Yell out a grunt, it will be more funny to the neighbors. Good luck!
Q:Does HAIR CEMENT help your hair grow?
No. Hair has its own timetable and a heavy duty setting gel will not make it grow faster. Hair cement is a heavy duty hair styling product designed to hold hair in just about any position with stiff results, withstanding wind, light rain, and even sleep. It can defy gravity and is specifically made for spike-type hair styles. This styling product is a paste-like substance that is delivered most commonly in a tube or a pot, but some manufacturers carry the product in a spray bottle or foam canister. Some brands include a temporary color in the paste, which can add a fun touch of color to a hairstyle.
Q:i have a really ginormous problem, attraction to cement?
well your last sentence sounded wrong...... but other than that i think its normal
Q:if you ate cement mix, could it set in your stomach?
Probably not because your stomach contains high levels of hydrochloric acid and it is contantly churning and digesting (you can't digest sand anyway) so the cement wouldn't set but it would probably make you very sick and it wouldn't taste very nice either lol!
Q:Is cement cheaper than wood?
The inexperienced woodworker and the very experienced person will be able to do these projects without any difficulty OKorder Each and every one of the thousands woodworking plans and projects which are available are so well written so that even if you've never tried Woodworking before, or if you have 2 left hands, you would find woodworking a breeze
Q:How to check content cement & concrete? What do we increase strength of concrete ?
...do the concrete cube test.....different countries have different standards... ,,generally...the cement acts as the bonding agent for the concrete mixture..and thus the main factor that determines the resistant factor to resist compression...
Q:considering buying a house with crumbling cement and dark paneling, is it doable to fix these...?
We've turned our house around and we had the same problems you did and more! It took 2 years, but our house was built in 1820. We had to put up vinyl, raise ceiling about a foot, level the house, un crumble the cement basement, and rip half the bathroom out to make the living room bigger. But yes very doable, and you will be getting compliments from your friends and neighbors on how you turned the place around.
Q:what is stronger than plaster but lighter than cement?
Aerate the cement and it should hold most of its structural integrity as well as reduce the overall mass.
Q:cement and concrete as composite?
concrete is made up of portland cement and aggregate (sand, gravel and rocks) and you add water in certain ratios.
Q:How a cement solution is prepared;;what is effect of quick setting of cement;;?
cement is an ingredient in concrete. It sets with the chemical reaction of Calcium carbonate (limestone) and water to form a hard substance.
