PRECAST SANDWICH ELEMENTS OF LIGHTWEIGHT AGGREGATE CONCRETE

This paper describes the production and documentation of precast elements of Lightweight Aggregate Concrete (LWAC) with an open structure. The LWAC produced is a no-slump, roller compacted concrete, with dry densities (p) in the range 500-1800kg/m (3rd power) and compressive strengths (f (sub c)) of 2-30 MPa in most elements, which are used as walls or as roof and floor slabs. The two alternative documentation procedures "Design by Testing" and "Design by Calculation" are discussed. The formulas in the CEN-standard from TC177 for bending tensile strength and element shear strength are verified by comparison with the experimental results.
