DEMOLITION OF CONCRETE WITH EXPANSIVE DEMOLITION AGENT

Caspases: cellular demolition experts.

Apoptosis is co-ordinated by a family of cysteine proteases, the caspases, that dismantle the cell by targeting a panoply of proteins for limited proteolysis. The mammalian caspase family contains 14 members, a subset of which participates in apoptosis, with the remainder likely to be involved in the processing of pro-inflammatory cytokines. Apical caspase activation events are typically initia...

Interactive Structural Demolition

We present a method for a structural simulation of destructible 3-dimensional metal frame buildings at interactive frame rates. Beams, floor slabs, and wall sections are simulated as rigid bodies and joined together by rigid constraints. Each constraint is given a set of breaking thresholds for the force and torque around each axis, allowing them to fail if the structure is overloaded or damage...

Properties of Concrete Paving Blocks and Hollow Tiles with Recycled Aggregate from Construction and Demolition Wastes

In recent years there has been an increasing tendency to recycle the wastes generated by building companies in the construction industry, demolition wastes being the most important in terms of volume. The aim of this work is to study the possibility of using recycled aggregates from construction and demolition wastes in the preparation of precast non-structural concretes. To that purpose, two d...

The Efficiency of Hybrid BNN-DWT for Predicting the Construction and Demolition Waste Concrete Strength

The current study focuses on two main goals. First, with the use of construction and demolition (C&D) of building materials, a new aggregate was produced and it was utilized for green concrete production. The compressive strength test confirmed the good function of C&DW aggregate concrete. This concrete did not show significant differences with natural sand concrete. Second, Backpropagation neu...
