Long-Term Service Life of Structural Lightweight Concrete Roman period : The first known use of lightweight concrete occurred more than 2000 years ago. There are several lightweight concrete structures in the Mediterranean region, but the three most notable structures were built during the early Roman Empire and include the Port of Cosa, the Pantheon Dome, Continue reading "Durability"
Why Would You Want To Make A Hypertufa Planter? The
Weight. The weight and thus its portability factor is one of the prime reasons to make a hypertufa planter. They are lighter than cement pots in comparison. Hypertufa can be heavy, especially the very large ones, but compared to one made of cement, the weight is less.
Lake Bonneville - Wikipedia
Lake Bonneville was the largest Late Pleistocene paleolake in the Great Basin of western North America. The Western Interior Seaway preceded Lake Bonneville. Lake Bonneville was a pluvial lake that formed in response to an increase in precipitation and a decrease in evaporation as a result of cooler temperatures. Lake Bonneville covered much of what is now western Utah and at its highest level

Mar 01, 2019· 1. Introduction. Travertines and tufas are spring-related carbonate deposits which occur in many different climate and geological settings. Groundwaters supersaturated in CaCO 3 are required for sedimentation of spring-related carbonates. The ions needed can be supplied by sedimentary carbonates, volcanic rocks, or also metamorphic rocks forming the aquifer (Özkul et al., 2002;
