Normal weight vs lightweight concrete
WebPortland State University WebConcrete is considered to be lightweight is the density is not more than 2200kg/m 3 (the density of normal weight concrete is assumed to be between 2300kg/m 3 and 2400kg/m 3) and a proportion of the aggregate should have a density of less than 2000kg/m 3 .

Web8 de jun. de 2009 · An important question always is how much this will cost. Lightweight aggregate concrete is about $20 to $30 per cubic yard higher than a normal weight mix. For internal curing, you may only be replacing about a third of the aggregate with lightweight so it may only add an extra $10 per cubic yard.
Web8 de jan. de 2011 · Lightweight concrete was added to PGSuper Version 2.4. The features are compatible back to LRFD 1st Edition 1994. Lightweight concrete is defined by LRFD 5.2 as concrete containing lightweight aggregate and having and air-dry unit weight not exceeding 0.120 kcf. Input of a unit weight is not enough to fully define lightweight … WebLightweight concretes can be produced with an over-dry density range of approximately 300 to a maximum of 2000 kg/m 3, with corresponding cube strengths from approximately 1 to over 60 MPa and thermal conductivities of 0.2 to 1.0 W/mK. These values can be compared with those for normal weight concrete of approximately 2100–2500 kg/m 3, …
