Waste materials are utilized with an increasing frequency in the building industry, during the last decades. The motivation is both environmental and economical. In this paper, waste ceramic powder produced at the grinding of hollow brick blocks used in precise-walling technologies, is applied as a partial replacement of siliceous aggregates of lime plasters. The designed plaster mixes are analyzed from the point of view of their basic physical, mechanical, hygric and thermal properties. The bulk density, matrix density, open porosity, compressive strength, bending strength, water vapor diffusion permeability, water vapor diffusion coefficient, water vapor diffusion resistance factor, thermal conductivity and specific heat capacity are the investigated parameters. A reference lime plaster is analyzed as well, for the sake of comparison. Experimental results show a remarkable enhancement of mechanical properties of the plasters with the increasing dosage of ceramic powder. Moreover, the thermal insulation properties are improved and the water vapor diffusion capability of the plasters with ceramic powder increases.

Combined Data

This study reports on type: variety-mode classification, digital stereomicroscopy, petrography, neutron activation analysis, and previously published reports and characterizes production and distribution of Mars Orange Paste Ware in the Middle Preclassic-period Maya Lowlands. The sample consists of 2028 sherds of Mars Orange Paste Ware from Holtun, Guatemala, and 4105 sherds reported from sites in Central Belize and Peten Guatemala. The combined data suggest Mars Orange Paste Ware was a “short-distance” trade ware produced in the northeastern Maya Lowlands and distributed from Central Belize to the west.

And Control

This chapter summarizes the archaeological and iconographic evidence from Structure 5C-01 that indicate rulership was established at the small center of El Achiotal in the Late Preclassic period. The symbolic vocabulary at El Achiotal suggests rulers were knowledgeable of the widespread ideology that was being institutionalized in the southern Maya lowlands as well as the more ancient symbolic vocabulary that represented the institution of kingship developed by the Middle Preclassic at La Venta and other centers in Mexico. Variables such as geographic location and control over knowledge provided Late Preclassic centers with leverage to negotiate their status and power within the broader regional geopolitics, thus challenging conventional models used to understand early political authority and its organization over the landscape.

Marine Shell

Extensive archaeological investigations at the site of Pacbitun, a medium-sized Maya center located in west-central Belize, have revealed the large-scale production of marine shell ornaments during Middle Preclassic period (900-300 B.C.). Non-local marine shell and the restricted nature of its distribution indicate that some degree of control may have been exerted over the production and/or distribution of marine shell or the finished shell products. The sheer quantities of shell working debris in the site core of Pacbitun suggest that these ornaments were intended for intra- or extra-community exchange. Two different scenarios are presented to account for the quantity and spatial distribution of Middle Preclassic shell and shell working materials at Pacbitun and in the Belize River valley.

This chapter summarizes archaeological data and interpretations regarding 13 E Groups from the Cival region mapped and excavated by the Holmul Archaeological Project between 2000 and 2015. In the Middle (1000-350 BCE) and Late Preclassic (350 BCE-0 CE) periods Cival was the main political and ritual center in this region of northeastern Petén. Over the course of the Late Preclassic Period, four additional E Groups were built at Cival and nine more have been found so far at surrounding minor centers. These data from E Group complexes provide a coherent sample of architectural chronology, dimension, orientation and evidence of ritual behavior. Excavations in the Cival Main Plaza provide the most complete example of a Middle Preclassic E Group available to date. The ritual function of Cival’s earliest E Group focused on solar hierophanies that uniquely connected, calendrical, metereological and geomantic observations within a single locality. Subsequent Late Preclassic complexes in the region were built following the same principles according to each site’s peculiar topographic setting. In accordance with their initial function as place-making devices for emerging communities, E Groups in the Late Preclassic Period were associated with the emergence of regional political systems as centers of religious and political interactions.
