摘要： According to one aspect, a plaster based construction material can include a gypsum based plaster, and at least 1 part by weight biochar per 100 parts by weight gypsum. The construction material can have a nail pull force according to ASTM C1396 of at least 51 lbf or a core hardness according to ASTM C473 Method B of at least 66 N.
According to another aspect, a plaster based construction material can include a gypsum based plaster, at least 1 part by weight bichar per 100 parts by weight gypsum, and a stable or unstable surfactant. The plaster based construction material may have a relatively improved mechanical strength.
