Abstract:
Presents a description of tests made on concrete floor specimens of various types to determine their resistance to wear and to investigate the character of deterioration of concrete floor surfaces due to traffic.-The results of these tests show that concrete floors provided with finish courses containing coarse aggregate up to about l/3 in. in size and an excess of pea gravel are definitely superior to concrete floors with a finish course containing fine sand only which are common in Sweden. Moreover, this investigation has helped to elucidate the causes of the often se- vere and detrimental dusting of concrete floors. The surface skin of concrete floors is of poor quality and is easily abraded. Dusting can be considerably Fe-duced if the poor surface skin is removed by machine grinding provided that the concrete below the surface skin is of first-rate quality. The paper concludes by proposing a detailed tentative specification for con-crete floor finish which differs in essentials from current Swedish practice.
