The best reaction for use in our hand warmers was the 'slaking' of lime. It generated enough heat for our purposes, and involved chemicals (water, calcium oxide and calcium hydroxide) that are ...

For decades, researchers believed that pozzolanic concrete was made by mixing slaked lime—a product of quicklime (calcium oxide) and water—with volcanic ash. This reaction created a tough ...

The thermochemical decomposition of limestone to produce lime, or calcium oxide—the primary precursor for cement production—accounts for about 60% of the CO 2 released, while the combustion of ...

Here are some ways neutralisation is used: Farmers use lime (calcium oxide) to neutralise acid soils. Your stomach contains hydrochloric acid, and too much of this causes indigestion. Antacid ...
