Iranians are having an ancient history in recognition and preparing building materials. Our ancestors’ buildings in different parts of the country, left the previous ages, specify its dimensions. Lime and mortar are the materials that have been used widely in ancient Iran.

Cement usage Start time is unknown in Iran, but the arrival of cement in Iran, carried out by foreigners from which to build the buildings, such as churches, embassies and installations of the port is used.

Old building materials with nowadays modern method did not have the required endurance and performance to build the economic infrastructure, therefore the need of new building materials has been inevitable that the cement is one of the most important ones in construction of buildings.

New projects such as public railway lines and buildings, bridges, tunnels and other buildings need a lot of cement pressingly, so the government had to import cement and the importing volumes were added each year so that in 1935 Iran was considered as the fourth cement importing country in the world.

Iran is geographically located in an area that is surrounded by Limestone Mountain, therefore the raw material for cement production in the country are plenty founded. The government took the decision to build a cement factory in Iran.  The required studies and researches were started to establish the first cement factory in 1928, and also the project‘s required raw materials storage estimation was began, in 1930 a contract with F L Smith  a Danish company was signed to build the plant, known as Ray cement 100 tons cement production capacity per day and with the state capital equal to 800.66 pounds sterling for machinery supply, and 800,133 pounds sterling to meet the power requirements. The factory asset was paid by government and from the sugar factory incomes. 

On December 28, 1933 the first cement kiln with a capacity of 100 tons per day came into operation, that was located seven kilometers south of Tehran, close to the Bibi Shahrbanu and Sorsore mountains in Ray Cement Company.

Due to the high demand for cement and inadequate production, the above mentioned plant with 200 tons capacity per day was purchased from germen Polizeyus Company in 1935 to meet the internal needs. Construction work of this line began in 1936 and in 1937 reached the production stage. The plant construction was to cost the equivalent of 18 million rials.

Cement reception by people actuated government to order the 3^rd production line with 300 tons capacity to Germany in 1938. Construction work of this unit began and about 80% by the year 1941 was conducted. Part of its machinery was also shipped. But with the occurrence of World War II the ship of containing the bulk of the machinery was confiscated by Allied forces in the Suez Canal vessel. 11 years later, in 1951, with an amendment to the contract with the Polizeyus company the Continuation of the Rey Cement Company third production line was resumed and in 1955 came into operation. So till 1951, only two cement kiln was installed with a capacity of 300 tons per day or in other words 90,000 tons per year. World War II caused a delay of 15 years in the capacity of the Iran cement industry.

Iran Cement Industry with 70 years’ experience in production is of industrial infrastructure that has deep relationship and bond with a wide variety of industries and service centers.

Iran with a production capacity of 85 million tons of cement production has the highest cement production capacity in the Middle East and could be classified in terms of global cement producer located among the first 15 countries.
