CELLULAR CONCRETES WITH AN VARIATROPIC STRUCTURE AT THE PRODUCT FORMING STAGE

چکیده
The paper presents a one-stage method of development results to obtaining effective structural and thermal insulation products based on cellular concrete with variatropic structure the study their properties. In addition, study's determining influence initial components quantitative ratio foam-aerated mixture technological regimes. For this purpose, model system [Ca(OH)2;Al;H2O;NaF] has been created. effect mixture's form filling (1.0÷0.7) perforation index walls formation properties is studied. Influence concretes strength characteristics them It confirmed that variable density from periphery have sufficiently good due low in central zone. Concurrently, it meets all required indicators strength, hardness erosion resistance high surface layer. At same time, absence sharp boundary prevents zone appearance contractive stresses condensate accumulation. experimental confirm possibility specified producing building elements higher than similar monotonic while maintaining material intensity.

متن کاملAn EPQ Model for Product Life Cycle (Maturity Stage) with Deteriorating Items and Shortages
A product life cycle is the life span of a product in which the period begins with the initial product specification and ends with the withdrawal from the market of both the product and its support. A product life cycle can be divided into several stages characterized by the revenue generated by the product. This study investigates inventory control policies in a manufacturing system for a si...
متن کاملDynamics of an eco-epidemic model with stage structure for predator
The predator-prey model with stage structure for predator is generalized in the context of ecoepidemiology, where the prey population is infected by a microparasite and the predator completely avoids consuming the infected prey. The intraspecific competition of infected prey is considered. All the equilibria are characterized and the existence of a Hopf bifurcation at the coexistence equilibriu...
متن کاملDevelopment of pneumatic cellular robots forming a mechanical structure
This study deals with group robots forming a mechanical structure. In this paper, we address the concrete motion mechanisms of the robots. Each robot has a cubic shape with pneumatic actuators. It rotates with a corner of the robot as an axis. To realize the movement, we propose two kinds of mechanical devices. One is a stabilization mechanism that the pneumatic actuator stably forms an arched ...
