Abstract: A method of monitoring the presence of personnel within a facility (S) and of monitoring the evacuation of the facility. A personnel registration system (2, 2a, 2b, 4) obtains data indicating the presence of a person. An interface computer (6) continuously receives data about people at the facility from a personnel server, and continuously supplies data to a monitoring server (9). A portable device (10a, 10b, c) is in data communication with the monitoring server and continuously receives data from the monitoring server. Upon evacuation of the facility, the portable device is taken to a mustering point (A, B, C) outside of the facility, and communicates (10) wirelessly with the monitoring server and continuously receives data from and sends data to the monitoring server. During evacuation of the facility the portable device logs the attendance of people at the mustering point and continuously communicates information to the monitoring server about people logged.

Abstract: A high early-strength cementitious composition comprising a hydraulic cement; and a combination admixture system wherein the combination admixture system comprises a polycarboxylate high range water reducing dispersant in combination with an accelerator and a retarder. The admixture allows for acceptable workability and development of high early-strength in cementitious compositions without the use of an external heat source.
