We　study　an　approximate　technique　for　determining　the　shapes　of　mixed　type　void　flaws　in　elastic　media　from　knowledge　of　the　ultrasonic　scattering　amplitudes.　It　is　well　known　that　the　technique　is　highly　effective　under　weak　scattering　conditions.　In　the　paper,　two　cement　paste　cylindrical　specimens　with　mixed　type　void　flaws　are　prepared　and　ultrasonic　measurements　are　carried　out　by　experimental　means.　The　measurement　area　is　restricted　in　the　plane　perpendicular　to　the　axis　of　cylindrical　specimen.　The　measured　wave　data　are　fed　into　the　approximate　technique　formula-the　Born　inversion　method　and　cross-sectional　image　is　obtained.　We　find　that　good　results　have　been　obtained　for　strong　scattering　void　flaws　such　as　mixed　type　void　flaws　in　cement　paste　cylindrical　specimens.　(C)　2013　Elsevier　Ltd.　All　rights　reserved.
