Final answer:
Concrete with a density of 135-165 lbs/ft^3 and compressive strength of 2,000 psi to over 8,000 psi is durable, versatile, and has varying strength for different uses. It features a high compressive strength with a lower shear strength and is valuable for reducing building load and providing thermal protection. The dynamics of pumping this concrete are based on flow rate, viscosity, and pressure to ensure laminar flow.
Step-by-step explanation:
Concrete with a density of 135-165 lbs/ft3 and a compressive strength ranging from 2,000 psi to over 8,000 psi has certain characteristics.
The density of concrete is a measure of its mass per unit volume. The density range provided indicates that the concrete is lightweight. This means that it has a lower mass compared to traditional concrete, making it easier to work with and transport.
The compressive strength of concrete is a measure of its ability to withstand compressive forces. The range specified indicates that the concrete is of high strength. This means that it can bear heavy loads and is suitable for structural applications.
