Practical Concrete Work for the School and Home | by H. Colin Campbell
Concrete has been the theme of many books. No excuse can be found for this one by claiming that the subject has not been written of before, yet the authors feel that there is a good excuse or reason for their efforts. While most of the volumes that have been written upon concrete are full of valuable information, the interested person has too frequently found that they contain but a little which really responds to his interest.
