Short History
LIMRA STONE is mined within 120 km distance to Antalya, from the historical Limra region of Finike District within 5 km distance to the sea. It is limestone which has a homogeneous physique and coloured light cream. It is been giving blocks in desired dimensions and portable sizes. It is looked for outer covering because of its light and isolating characteristic feature and it receives appreciation in domestic and foreign market.

Physical - Mechanical Analysis Evaluation
Unit Volume - Specific Weight:
In the weight per unit of volume experiment according to T.S.E.(Turkish Standards Institution) 2513, average weight per unit of volume is found 2.2 gr/cm³ and average specific weight is identified 2.6 gr/cm³. Specific weight of natural stones which will be used for building and outer covering stones except travertine must be over 2.55 gr/cm³ according to T.S. (Turkish Standards) 2513 and LIMRA complies with this standard.

Water Content - Water Absorption:
The dissolution of natural stones with water effect is been an important case especially for stones which are used as outer covering materials. Natural stones are changed with physical and chemical effects under atmosphere conditions even if it happens slowly in process of time. Dissolution intensity is not same at all and it is changed by the chemical compound, chemistry and water absorption of stones. The natural stones that are used as building and outer covering stones must have water absorption capability in weight under atmosphere pressure is lower than 7.5% and water absorption capability in volume under atmosphere pressure is lower than 12% according to T.S. 1910. LIMRA's water absorption capability in weight is detected 5.1% and its water absorption capability in volume under atmosphere pressure is detected 11.3%. These symptoms show that LIMRA complies with T.S. 1910 in consideration of water content and water absorption.

Thermal Insulation:
It provides thermal insulation three times more than other known marbles. Its thermal permeability coefficient   is three times lower than Burdur beige and salome and it is 0.8 W/m.K.

Apparent Porosity:
Those are identified that LIMRA has apparent porosity ratio is 11.3% and compactness ratio 86.7%. The natural stones which will be used for outer covering except travertine must have an apparent porosity ratio below 12%, according to T.S. 1910..
Frost Resistance: 
Frost Resistance is a requirement case at natural stones which are used for outer covering in Building Sector. After frost pressure resistance reduction of items that are used for cladding must be below 5% and after frost mass loss of items that are used for cladding must be below 1% according to T.S. 1910. In the experiments that were done according to T.S. 699, LIMRA has a ratio of 0.2% on after frost mass loss and has a ratio of 0.28‰ on after frost pressure resistance reduction. When we keep in view for after frost mass loss and pressure resistance reduction, LIMRA complies with T.S. 1910 in that mass loss..
