Generally, it is known as the Box-Jenkins autoregressive integrated moving average (ARIMA). CHRISTIANSE [1] and PARK et al [2] designed......
]. Other cations, such as phosphonium, pyridinium and imidazolium are excellent modifiers due to their higher thermal stability. For instance, PATEL et al [16] found that phosphonium montmorillonites (P-MMTs... and purify water rather than to cause secondary pollution. There are few reports on studying the antibacterial activity of P-MMTs yet. Only HERRERA et al [15] reported that cetylpyridinium modified......
. It was found that an increase in unit weight resulted in a reduction in the fire resistance of the concretes. TURKER et al[4] investigated the micro-structure and strength of concretes exposed to fire... pumice was used[12].According to KONG et al[12], ABELES and BARDHAN-ROY[13], concretes containing lightweight aggregate preserve their strength up to nearly 500 ℃. It was stated that the residual......
