Fluctuations in temperature and relative humidity could cause damage to museum artefacts and may require higher energy needs than necessary.

Structure and Properties of Portland-Limestone Cements Synthesized with Biologically Architected Cal that of reagent grade CaCO.. X-ray diffraction indicated no differences in mineralogy between reagent-grade and biogenic CaCO.. The use of biogenic CaCO. as a limestone filler led to (i) increased water demand at the higher replacements, which was countered by using a superplasticizer, and (ii) enhfreight 发表于 2025-3-28 08:14:09
