Camera lucida method for measuring air voids in hardened concrete
Description of method which involves use of camera lucida in conjunction with microscope; air content of hardened concrete as determined compares satisfactorily with results obtained by other methods; method is applicable to study of weather resistance of concretes from structures of various ages to determine extent to which entrained air may have contributed to weather resistance. (See also - discussion v 19 n 4 pt 2 Dec 1947 p 1040) (5 p)
