When sediments settle in one area, they can eventually compact and cement together to form sedimentary rock over time. The process of lithification, which includes compaction and cementation, is key in transforming loose sediments into solid rock. This can occur in various environments such as river deltas, lakes, and oceans.
The force that squeezes sediments together to form sedimentary rocks comes from the weight of additional sediment deposited on top of them, as well as tectonic forces from the Earth's movement. This pressure causes the grains of sediment to compact and cement together over time, creating solid sedimentary rocks.
The object is called a sedimentary rock and is formed through the process of sedimentation, which involves the accumulation of sediments over time. As the sediments compact and cement together, they form a solid rock.
Moving water drops sediments it is carrying when its velocity slows down. This can happen when the water enters a wider channel, encounters obstacles like rocks or vegetation, or when the gradient of the river decreases, allowing sediments to settle out of suspension.
Minerals that act like glue or cement in sediments are primarily called cementing agents, with silica, calcite, and iron oxides being the most common types. During the process of lithification, these minerals precipitate from groundwater and fill the spaces between sediment grains, effectively binding them together. This cementation process is crucial for the formation of sedimentary rocks, providing structural integrity and stability to the sediment layers.
The lime content that is found in cement causes cement to heat.
1. What are the causes of unsoundness of cement?
Improper tampering, bad cement mixture, improper mixture of cement and water during laying.
sediments are transported by ocean rift, streams, river currents, wind (air). they are deposited according to size. The largest sediments are deposited first. The sediments settle into the sand and are carried by the stream. Near the mouth of the stream where the water moves slowly the small sediments settle out. The larger sediments get carried by the river into the sea then the samller sediments. The sea water dissolved minerals and soak the sediments and cement together. This eventually forms sediments.
The rock formed when dissolved minerals cement sediments together is called sedimentary rock. This process occurs over time through the compaction and cementation of particles such as sand, silt, and clay. Examples of sedimentary rocks include sandstone, limestone, and shale.
The sediments build up on the floor of the stream, ocean, river, or lake and causes the water to lower.

Moisture under hairline cracks.
sediment causes H2O to discolor. also sediment causes some submerged vegetation to die.
To make cement in alchemy, you typically combine limestone and clay together. These two materials are heated in a kiln to high temperatures, which causes chemical reactions that result in the creation of cement.
Sediments (sand, clay, boulders etc) are derived from the erosion of preexisting rocks by snow, ice, water and wind. Eventually these sediments settle and are covered by more sediments. As the weight of overlying sediments builds up the pressure and minerals dissolved in and carried by groundwater cement the sediment particles together to form a new rock layer. This new rock is called a sedimentary rock.
