Structural lightweight concrete offers design flexibility and substantial cost savings by providing reduced dead load, reduced seismic loading, longer spans, better fire ratings, thinner sections, decreased story height, smaller size structural members, less reinforcing steel, and lower foundations costs. Structural lightweight concrete precast elements have reduced trucking and placement costs. The excellent durability performance of structural lightweight concrete made with expanded shale, clay or slate (ESCS) structural lightweight aggregate is a result of the ceramic nature of the aggregate, and its exceptional bond to and elastic compatibility with the cementitious matrix.
Structural lightweight aggregate's cellular structure provides internal curing through water entrainment which is especially beneficial for high-performance concrete, (HPC). Internal curing improves the aggregate/paste contact zone which mitigates micro cracking.
Compared with ordinary concrete, lightweight concrete using ESCS lightweight aggregate has better thermal properties, higher fire ratings, reduced autogenous shrinkage, improved contact zone between aggregate and cement matrix, less micro-cracking as a result of better elastic compatibility, and better shock and sound absorption, high-performance lightweight aggregate concrete also has less cracking and improved skid resistance and is readily placed by pumping.
A $2.6-billion stadium taking shape on the outskirts of Los Angeles will transform an old horse track into one of the area’s most eagerly anticipated developments. Los Angeles Stadium at Hollywood Park will serve as the new home of the LA Rams while the surrounding area will become a small city in itself.
When Costco decided to add an eighth level, and some 290 more parking spaces, to the parking structure at their headquarters in Issaquah, WA -- already designed and under construction -- lightweight aggregate from Arcosa Lightweight helped provide the solution.
Cranes tower above Cobb County Georgia’s Cumberland District. Down below, SunTrust Park, the new home of the Atlanta Braves, is taking shape. The ballpark and mixed-use development is the first of its kind: a place where fans can shop, eat and even live long after the game ends.
Houston’s latest skyscraper, Market Square Tower, soars well above Preston Street. The stunning height of this residential high-rise is made possible by structural lightweight aggregate.
When constructing high-rise buildings, every floor has to be strong enough to support the loads imposed on each level, and also provide the fire resistance required by the building code.
