Cement compositions comprising a modified styrenic block copolymers and methods for making/using the same are disclosed. The modified styrenic block copolymer has at least one monoalkenyl arene polymer block A, at least one conjugated diene polymer block B, and at least an epoxy functional group or derivative thereof. The modified styrenic block copolymer has a degree of epoxidation of up to 10-90%. The cement composition can be used in subterranean applications, as well as in building and construction materials. The modified styrenic block copolymers swell upon contact water or other aqueous fluids to seal cracks in the cement.

Cement compositions and methods of preparation thereof

A cleaning composition is disclosed comprising a method of cleaning a substrate to remove a residue from the substrate by using a cleaning composition comprising (a) a decarboxylated rosin acid (DCR), and (b) optionally a diluent. The residue is selected from soil, dirt, sand, food, oil, grease, paint, ink, glue, adhesive, sealant, wax, tar, graffiti, asphalt, buffing compounds, cutting fluids, and mixtures thereof. At least 0.3 wt.% of the residue is removed from the substrate per cleaning cycle, based on total weight of the residue present on the substrate. The cleaning composition is stable and is effective in removing the residue from hard or soft substrates.
