The feasibility of using concrete polymer composites as materials of construction for handling hot brine was demonstrated in 1972. The results from these tests indicated that the composites had long-term stability in seawater at 177°C and in acid solutions. Since then the work has been extended to develop materials for use in geothermal systems. To date, high temperature polymer concrete systems have been formulated, and laboratory and field tests performed in brine, flashing brine, and steam at temperatures up to 240°C. Results are available from field exposures of up to 12 months in four geothermal environments. Testing at two other sites is in progress. Good durability is indicated. Based upon these results, potential applications in geothermal processes have been identified.

A program to determine if concrete polymer materials can be utilized as materials of construction in geothermal processes has been in progress since April 1974. Since that time high temperature polymer concrete formulations have been developed, laboratory tests performed in simulated geothermal environments, field testing initiated at four geothermal sites, and economic studies started. To date, field test results have been obtained for 180-day exposures to dry steam, flashing brine, and hot water. Good durability is indicated. Work accomplished during the period April 1--June 30, 1976 is described in the current report.

A serious problem in the development of geothermal energy is that suitable, durable, and economical construction materials are not readily available. Hot brine and other aerated geothermal fluids are highly corrosive and attack most conventional construction materials. Brookhaven National Laboratory has been investigating the use of concrete polymer materials as alternative construction materials for geothermal processes. To date, successful field tests have been demonstrated at the Geyesers, the U.S. Bureau of Mines Corrosion Facility, and the East Mesa Geothermal Facility. This report is a survey of field and laboratory evaluations of concrete polymer materials that have been shown to be durable and economical as alternative construction materials.

The availability of durable and economic materials of construction for handling hot brine and steam is a serious problem in the development of geothermal energy. The standard grouting materials used to cement well casings into the ground are severely attacked by brine and steam at temperatures>200°C. Progress in the research program to determine if concrete--polymer composite materials can be utilized in geothermal power systems, initiated in April 1974, is reported. (WHK).

A program to determine if concrete polymer materials can be utilized as materials of construction in geothermal processes is in progress. To date, several high temperature polymer concrete systems have been formulated, laboratory and field tests performed in brine, flashing brine, and steam at temperatures up to 260 deg C (500 deg F), and economic studies started. Laboratory data for exposure times up to 2 years are available. Results are also available from field exposures of up to 12 months in four geothermal environments. Good durability is indicated. Work at two of these sites is continuing and tests have recently been initiated at two locations in the Imperial Valley. (MM).
