What Is PPC Cement? Portland Pozzolana cement is an incorporated cement produced in that certain ratio by the synthesis and characterization of OPC cement from pozzolana materials. It's also generally referred to as PPC cement. PPC type cement is a form of Portland cement distinguished by the existence of pozzolana particles such as fly …

Pozzolan. Definition: a siliceous or silico-aluminous material that will, in finely divided form and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperatures to form compounds having cementitious properties (there are both natural and artificial pozzolans).-.

Basalt is an igneous rock that developed during the cooling of magma during the earth's early eras. A pozzolana is a substance capable of interacting with calcium hydroxide (Ca (OH) 2) in the presence of water at room temperature to produce cementitious compounds (as C-S-H gel) []. In recent years, many researches were …

The major focus of CO2 reduction in the cement industry is in naturally pozzolanic materials such as a group of raw materials referred to as calcined clays – naturally occurring clay deposits that are 'pozzolanic' (i.e., acts like cement) when heated in a kiln to around 700-800°C [5]. The term Pozzolanic derives from the Roman use of ...

A. A pozzolan is a siliceous or siliceous and aluminous material that in itself possesses little or no cementitious value but will, in finely divided form and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperatures to form compounds having cementitious properties. It is therefore classified as cementitious ...

Natural pozzolans. Used by the ancient Greeks and Romans to make concrete, natural pozzolans are now used to replace the amount of clinker used in cement, creating a more sustainable building material. Pozzolanic materials occur both naturally in the earth's crust, as well as being produced as by-products of various industrial processes (e.g ...

Unlike natural pozzolans, artificial pozzolanic materials are industrial by-products or materials that have undergone processing or heat treatment. Such processes modify their chemical and/or physical structure. Thereby, artificial pozzolans are classified into two main groups, industrial by-products and treated calcined materials.
