What else can I help you with?
What can be heated with clay to make cement?
calcium carbonate (limestone)
What substance is made when limestone and clay are heated together?
Limestone, CaCO3 decomposes into quicklime, CaO, and carbon dioxide, CO2, when heated. The reaction is: CaCO3 + heat --> CaO + CO2.
How is cement formed from limestone?
Cement is formed from limestone through a process called calcination, where limestone (calcium carbonate) is heated at a high temperature to break it down into lime (calcium oxide) and carbon dioxide. The lime is then further processed and combined with other materials like clay to create cement.
When limestone clay is heated what happens?
makes ceramic or porcelaine
What does heat limestone with clay produce?
Heating limestone with clay produces cement, which is a key component in the production of concrete. This process is known as calcination, where limestone and clay ingredients are mixed and heated to high temperatures to form a substance called clinker.
How does clay turn into limestone?
Clay can turn into limestone through a process called diagenesis, where the clay particles are subjected to compaction and cementation, forming a new rock material. Over time, the minerals in the clay are altered and precipitate out to form calcium carbonate, which is the primary mineral in limestone.
How is natural cements formed?
It is formed by natural processes by usually involving a mixture of limestone and clay.
Which is the hardest granite clay chalk Jurassic limestone or carboniferous limestone?
Among granite, clay, chalk, Jurassic limestone, and Carboniferous limestone, granite is generally considered the hardest material. Granite is an igneous rock formed from the slow crystallization of magma, making it much denser and more durable than sedimentary rocks like chalk and limestone. Carboniferous limestone is relatively hard but not as tough as granite. Therefore, granite stands out as the hardest of these materials.
What do you call a mixture of crushed limestone and clay?
A mixture of crushed limestone and clay is commonly referred to as "raw meal" in the context of cement production. This mixture is typically combined and heated in a kiln to produce clinker, which is then ground to create cement. The proportions of limestone and clay can vary depending on the desired properties of the final product.
How do you make cement on alchemy?
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.
Which is harder limestone or clay?
Limestone would be potentially harder until the clay is fired. The problem we have here is that "clay" is an ambiguous term. There is no homogenous or standard formula for clay. However, clays can generally be formed and baked to become set and hard. This is called firing. Fired clay tends to be quite hard, and depending on the formula, might be harder than limestone.
Is cement a mixture of limestone and silicon dioxide?
Cement is a powdered substance made primarily from limestone, clay, and other minerals like iron ore and gypsum. It is not a direct mixture of limestone and silicon dioxide. The limestone and clay are heated together to form a compound called clinker, which is then ground into a fine powder to make cement.
