摘要： Compositions comprising crosslinked polysaccharides, particularly levan and/or dextran, may provide advantageous benefits when admixed with concrete blends. Suitable compositions may comprise a biologically sourced surfactant, and a crosslinked polysaccharide, in which the crosslinked polysaccharide comprises at least one crosslinking group bonded via ether linkages to a first polysaccharide chain and a second polysaccharide chain. Concrete blends may comprise such compositions, a cement and water. Methods for forming and/or using the concrete blends may comprise allowing the concrete blends to form a hardened mass.
