C 127 and C 128 have recently changed to allow the test method to be used for lightweight aggregates. In C 330 the density factor has in the past been determined by a test method in the annex of ACI 211.2. This test method was the only published method of determining the density factor of lightweight aggregates available to the committee until the amendments to C 127 and C 128.
