Abstract:
The quality of concrete in the office and laboratory building of the Portland Cement Association was successfully controlled, without the use of special equipment and without the need of a testing organization, solely by means of a specification based on the control of the quantity of mixing water. This specification fixed only the proportion of water to cement; the aggregate proportions were left entirely to the judgement of the contractor, with the limitation that plastic and workable mixes be produced.
