Disclosed is a new composite material comprising nanocellulose and hemp or a hemp-derived component, such as pure hemp, hemp bast fibers, hemp inner fibers, hemp shives, hemp leaves, hemp seeds, or ground hemp. The nanocellulose may be hydrophobic or hydrophilic, and may include cellulose nanocrystals, cellulose nanofibrils, cellulose microfibrils, or a combination thereof. This invention provides construction blocks or panels; engineered parts; fire-resistant objects; coatings; containers; textile compositions; and fabric materials, for example. The composite material may also include one or more additives to modify mechanical, thermal, chemical, and/or electrical properties. The addition of nanocellulose can improve the mechanical properties of hemp-containing concrete mixtures to improve compressive strength for construction purposes.

To provide a blast furnace slag-type paint using a liquid inorganic material composed of a fluid suspension.

A blast furnace slag-type two-part paint in which a stabilized aqueous suspension containing the following blast furnace slags is contained as the main agent, an alkaline liquid having dissolved therein sodium silicate, sodium carbonate, or potassium carbonate that induces a hydraulic reaction of the suspension serves as the hydraulic reaction inducer, and the main agent and the hydraulic reaction inducer are separately packaged.

<Components of the main agent> (A) 0.5 to 42% by weight of a high-blast-furnace-slag-content blast furnace slag having a blast furnace slag content of 60% or more with respect to the total weight of the blast furnace slag; (B) 0.1 to 20% by weight of a blocking agent containing a phosphorus-containing compound; (C) 0.3 to 5%, preferably 0.3 to 2.5% of a blocking agent differing from a phosphorus-containing compound; (D) water retention agent; others.

A method of making a cement composite can include contacting an aqueous solution comprising calcium ions with a carbon dioxide source producing a carbonated aqueous solution. Fine particles can be submerged in the carbonated aqueous solution to produce microaggregate particles comprising the fine particles coated with calcium carbonate. The microaggregate particles can be combined with cement particles to produce the cement composite. The cement composite can be used in cementing applications for hydrocarbon wells including for casing liners and well plugs.

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.
