    Abstract: A hydrated cementitious blend, and method of using same, the blend comprising: a dry cementitious blend comprising the following, based on the total weight of the dry cementitious blend: aggregate comprising less than 3 wt. % calcium, based on the total weight of the aggregate; from about 75 wt. % to 82 wt. % pozzolonic material comprising improved ash comprising particles meeting the ASTM C 989-2010 testing protocol for grade 100 slag quality or higher, the improved ash being selected from the group consisting of fly ash, calcined or uncalcined volcanic ash, rice hull ash, and combinations thereof; a catalytically effective quantity of catalyst selected from the group consisting of alkali-containing zeolite, alkali-containing feldspathoid, and combinations thereof; and, an amount of water reducing component; the hydrated cementitious blend further comprising an amount of water producing a ratio of water to cementitious blend of from about 0.20 to about 0.30 and a slump of 6 or more; the hydrated cementitious blend producing a product cement exhibiting a compressive strength of 4000 psi or more after curing for 28 days at 75° F. or more.

    Abstract: An electronic chart system in which charts of the earth are stored in digital representation and communicated to the operator by a visual display. Through the use of a Loran-C receiver or the like, the system additionally plots the carrier's position on the visual representation of the chart. The visual display is a cathode ray tube on which the visual representation is compressed or expanded to meet the demands of the operator so that the appropriate resolution is thereby obtained. To minimize memory size an encoding format is used which provides a data word for indicating the first physical element of the run line, a data word for the number of runs per line and data words for the lengths of N-1 runs of up to two variables for each line of the chart.
