b) Binder (usually straw or animal hair), aggregate (usually sand), and water
c) Binder (usually lime), aggregate (usually gravel), and water
d) Binder (usually gypsum), aggregate (usually limestone), and water
Answer:
a) Binder (usually Portland cement), aggregate (usually sand), and water
Modern stucco is composed mainly of a binder (usually Portland cement), aggregate (usually sand), and water. These three main components form the foundation of modern stucco applications for construction and architectural finishes.
Portland cement is commonly used as the binder in modern stucco due to its durability and strength. Sand is the typical aggregate added to the mix to provide texture and bulk. Water is essential to help create a workable paste that can be applied to surfaces.
While other additives may be included to enhance properties like durability, flexibility, and water resistance, the traditional materials like straw or animal hair are not typically part of the modern stucco composition.
