Abstract: Systems, computer program products, and methods are described herein for secure access control using dynamic resource replication. The present invention is configured to electronically receive, from a computing device of a user, a request to generate a resource access path to access a resource; determine one or more resource requirements associated with the resource; determine an authentication level associated with the user; initiate a resource replication engine on the one or more resource requirements and the authentication level associated with the user; determine, using the resource replication engine, that the one or more requirements and the authentication level associated with the user meets one or more conditions for a replication process; and generate, using the resource replication engine, the resource access path and a plurality of replicate resource access paths.

Abstract: A system for authorizing secured access using cryptographic hash value validations is provided. In particular, the system may receive requests from users and/or computing systems to obtain secured access a particular resource or to execute a certain process. In response, the system may require that the user and/or computing system complete additional required steps (e.g., a computation) before being granted access to the resources or processes. In this way, the system may prevent unauthorized or unintended access to the system's resources or processes.

Abstract: A durable, nailable, lightweight and fire resistant fiber cement article that can be a cost-effective substitute for conventional building materials is provided. The fiber cement article can be profiled to resemble a roofing article such as a wood shake or slate. The fiber cement article incorporates a hydrophobe and a viscosity enhancing agent that are each selected to control the rate of hydration of the binder. The fiber cement article is durable, is walkable and nailable without cracking during installation and maintains walkablilty after exposure in service.

Abstract: A formulation for preparing a cementitious product comprising a cementitious material, a siliceous material, and a low bulk density material being substantially calcium silicate hydrate and including unreacted siliceous reactant. A method of forming a cementitious product comprises adding a cementitious material, a siliceous material and a low bulk density material to water to form a slurry, forming a green shaped article from the slurry and curing the article in an autoclave, wherein the low bulk density material is substantially calcium silicate hydrate and includes unreacted siliceous reactant.
