Asphalt packets and methods of making and using asphalt packets are provided. For example, an asphalt packet can be provided that include asphalt that comprises an inner volume and a polymer film outer coating that encapsulates the inner volume of the asphalt. The polymer film outer coating can be non-tacky at ambient temperatures to permit stacking of a plurality of asphalt packets under weight without causing the packets to agglomerate.

An anti-corrosive concrete grouting material for coastal structure connection and a method for preparing the same, belonging to the technical field of anti-corrosion of coastal assembled structure connectors. The grouting material includes the following components: expansible compound cement, slag sand, fly ash (FA), polyvinyl alcohol (PVA) (containing an oxidant and a catalyst), graphene oxide (GO), a water reducer, an adjusting admixture, a defoaming agent, a mineral admixture and water. A shrinkage-free effect of the grouting material is realized through internal curing of GO-PVA hydrogel, micro-expansion of the compound cement and shrinkage reduction effect of the FA; an energy storage effect of a GO-PVA hydrogel micro-capacitor is exerted to avoid formation of a reinforcement corrosion micro-battery in a grouting material sleeve, a reinforcement corrosion self-immune effect is achieved, seawater corrosion resistance of the grouting material is improved by the slag sand, and it has huge economic and environmental protection benefits.
