  • This study is concerned with the development of the SL inorganic floor covering. First, volatile organic compounds, inorganic test profile on the SL through the flooring is environment-friendly inorganic noncombustible floor finishes the event of fire toxic gases (such as volatile organic compounds) emissions have been identified as not at all. Second, SL-breathable material, the concrete floor to prevent aging, long life, which are three levels of noise, shock-absorbing function was decreased. Third, SL economic analysis of mineral flooring terrazzo tile floors compared with the normal material. On a terrazzo tile cost 13,500 won ~ 24,500 won, but It have found that, in terms of labor SL 36,899 won ~ 38,899 won flooring mineral balance. Occurs in the total amount when compared with terrazzo tile floors and 25,399 won 3T, 5T and economical analysis concludes that the original 12,399 won.

  • This paper is the result of an investigation of a PORTABLE SLIP METER(ONO PPSM) by means of an experiment to determine its validity as a slip meter. ONO PPSM is a portable slip meter that was designed to address the weak points of PULL SLIP METER(O-Y PSM), which can be used to obtain an accurate measurement of slip resistance, but is very heavy and difficult to operate. To determine the stability of the measurement result of ONO PPSM, we measured the slip resistance against 4 different kind of floor materials. Our findings showed that the coefficient of variability of CSR' is less than 0.05. Furthermore, we verified the relationship between CSR' and CSR. More specifically, by performing the slip test against 7 different kinds of inorganic matter floor materials, we increased the usability of ONO PPSM as a slip meter by suggesting a method of sharing the evaluation index of slip of CSR' and C.S.R.
