- Q: apparently fault breccia is a cataclasite, which are cemented rocks. However, my notes say that fault breccia consists of angular fragments set in an un-cemented matrix of wall-rock material.
- Pressure is the key factor in the formation of a fault breccia. The term breccia is used to describe the coarser grained types. Much finer fault zone rocks are actually clay sized particles. These can be lithified by pressure (no cement). Mylonites would be an example. Perhaps the rocks in question are a combination of the two. (?)
- Q: whats heavier when set up, cement or plaster?
- Cement-- concrete that is, a lot of bonding agents are also called cement-- is heavier, because the water stays in it when it is set. Plaster sets up with the water dried out of it.
- Q: My father has been using a really loud and strong nail gun to mount stuff in our new place that has cement walls. I did some research and found that you should drill a hole and do a bunch of other stuff as safety precautions. The website i found said that if there was an earthquake, the walls would crumble if you used a nail straight into cement. Is this true?I live in an area where we dont even have earthquakes often at all, which is Southern Ontario, Canada, but im still a little concerned because we had one last summer. Also, We live on the 10th floor, so if an earthquake does happen, it would shake a lot more up here. He also has been mounting stuff on the cement ceiling as well.Should I be concerned?
- No. Always drill into cement or concrete. Drilling makes a cleaner hole without cracks. When you crack cement, water and get in and when it freezes and melts it expands and contracts, further cracking the cement and allowing more water in. Salts in the water and also dissolve chalk in the cement and water can rust the re-bar if it gets to them. If you think about it, a drill uses a screw to pull material out of the wall. A nail merely pushes it out of the way. Since cement isn't that flexible, it tends to crack when expanding or deforming. A drill hole also makes a more secure anchoring point, since you don't have cracks around it and the spiral hole gives more grip on bolts you wish to put in it. There are lots of how to videos on this, but use a concrete bit and use liberal amounts of water on the bit. This both cool the bit and helps dampen the vibration caused by the drilling.
- Q: It is for 3 posts for a small fence/barrier
- THE CEMENT WILL SET UP--BUT NOT BE AS STRONG AS CONCRETE-BECAUSE IT DOESNT HAVE SAND AND GRAVEL--IT WILL CRACK AND THE POST WILL BECOME LOOSE-- IF THERE IS NO WEIGHT PUSHING ON THE FENCE--IT WILL PROBABLY BE ALL RIGHT
- Q: history of the development of cement?
- Cement history Throughout history, cementing materials have played a vital role. They were used widely in the ancient world. The Egyptians used calcined gypsum as a cement. The Greeks and Romans used lime made by heating limestone and added sand to make mortar, with coarser stones for concrete. The Romans found that a cement could be made which set under water and this was used for the construction of harbours. The cement was made by adding crushed volcanic ash to lime and was later called a pozzolanic cement, named after the village of Pozzuoli near Vesuvius. In places such as Britain, where volcanic ash was scarce, crushed brick or tile was used instead. The Romans were therefore probably the first to manipulate the properties of cementitious materials for specific applications and situations.
- Q: My sister is pouring a sidewalk alongside her house, and wants to have bare foot imprints of her and her two daughters. Its not my thing, but is this safe? I don't think wet cement can hurt you, but is it healthy to go barefootin' in, haha?
- I haven't worked too much with concrete... But! I'm thinking that it wouldn't hurt to put some vaseline on those little feet. I don't think the vaseline will hurt the cement. It might slow the drying process just a bit..... I don't know. You could always cover the cement with some press n' seal or other thin plastic...... the shape of the foot should still be made. I'm curious about this now..... You know, they do have kits sold at the arts crafts store...for kid's to making stepping stones. Maybe you should check one of those out first......
- Q: I like for my students to use rubber cement in the classroom. The school distict made us quit using it since it is toxic. I read somewhere that there is a new product that is like rubber cement, just nontoxic.
- Anything regional. Champagne, Stilton cheese, Melton Mowbray Pork Pies.
- Q: What is difference Between Cement Paste And Mortar?
- cement paste is just cement powder and water...mortar is cement, lime, sand and water...
- Q: Is cement is better than concrete to build weights?
- be more specific
