THE MICROSCOPY OF CONCRETE

CONCRETE INVESTIGATIONS ARE GENERALLY PERFORMED WITH THE POLARIZING MICROSCOPE WITH TRANSMITTED LIGHT BOTH ON THIN SECTIONS AND ON SCATTER SPECIMENS. THE POSSIBILITIES OF CONCRETE MICROSCOPY ARE SURVEYED WITH REFERENCE TO PHOTOMICROGRAPHS. FIRST, IT IS SHOWN HOW, WITH THE AID OF THE MICROSCOPE, UNUSED CEMENTS OF DIFFERENT KINDS CAN BE DETERMINED AND THE MINERALOGICAL CONSTITUTION OF THE AGGREGATES CAN BE JUDGED. WITH A LITTLE EXPERIENCE THESE INVESTIGATIONS CAN BE PERFORMED ALSO ON HARDENED CONCRETE, AND THEY ADDITIONALLY ENABLE THE CALCIUM HYDROXIDE TO BE DETECTED WHICH IS FORMED IN THE HYDRATION OF THE CEMENT. OF ESPECIAL IMPORTANCE IS THE MICROSCOPIC EXAMINATION OF NEWLY FORMED COMPOUNDS IN AND ON CONCRETE. IN THIS WAY VALUABLE INDICATIONS ARE OFTEN OBTAINED AS TO THE REACTIONS CAUSED BY CARBON DIOXIDE AND BY SULFATES. IN ADDITION, THE EXAMINATION OF CRUSTS AND STALACTITE FORMATIONS AND OF EFFLORESCENCE PHENOMENA PROVIDES INFORMATION OF THE MANNER IN WHICH THEY DEVELOPED. /AUTHOR/
