At the same time changes in the dampness of soil were researched.}, abstract={The results showed a considerable influence of dampness on firmness. The moisture content in soil masses in August was smaller almost 100% in comparison with results got in May 2002. The depth of penetration of soils in August was only about 6,4 cm smaller than this got in May, however the resistances on penetrometer were larg-er about 300%.}, type={artykuł}, title={Badania zwięzłości i wilgotności utworów glebowych powstałych w wyniku działalności przemysłu wydobywczego kruszywa budowlanego = Research into the firmness and dampness of formations created as a result of activiies of the extractive industry of building aggregate}, keywords={rekultywacja, zwięzłość - właściwość fizyczna, wilgotność - właściwość fizyczna, reclamation, firmness - physical properties, dampness - physical properties}, }
