A lost circulation material (LCM) is provided having an alkaline nanosilica dispersion and a polyester activator. The alkaline nanosilica dispersion and the polyester activator may form a gelled solid after interaction over a contact period. Methods of lost circulation control using the LCM are also provided.

Devices, systems, and methods of the present disclosure are generally directed to building material including particles of a polymer in an irradiated form, a cement including calcium oxide, and at least one additive including silicon dioxide. In cement paste formed from a mixture of these components, the polymer in the irradiated form may decrease porosity as compared to porosity of cement paste formed without the polymer, and a combination of the silicon dioxide and the calcium oxide may form high-density phases in the cement paste. With these characteristics, such cement paste may exhibit at least the same compressive strength as cement paste formed from the cement by itself. Thus, in certain instances, the particles of the polymer may displace a portion of the cement in a manner that maintains compressive strength while facilitating reduction of greenhouse gas emissions associated with cement paste formation.

A water-impermeable waterproof asphalt concrete composition having styrene isoprene styrene (SIS). The composition's waterproof performance due to its high cohesion and adhesion. The composition is durable and is not easily rutted, aged and/or stripped. In addition, the composition has a performance grade of PG 82-34, and can prevent water penetration and potholes. Furthermore, the asphalt concrete for prime coating and waterproof asphalt concrete can be applied to form an integrated structure by using a mixing/feeding system and can also be easily placed on site.
