Synthesis and Fabrication

 * sand hydrogel scaffold
 * fortified by calcium carbonate biomineralization
 * performed by synechococcus

Properties

 * reactive to humidity and temperature switches
 * operate best in 100% humidity, and viability of the cells decreases with humidity decreases
 * biomineralization increases from generation to generation
 * compressive strength similar to Portland-cement based mortars
 * modulus - 293.9 MPa
 * strain - .0169
 * max stress - 3.6 MPa
 * multiple generations of the material can be grown from one parent generation by introducing new sand hydrogel scaffolding
 * cells found to operate nearly as well at 50% humidity vs 100% humidity
 * important because most environments have a humidity of at least 50%

Uses

 * environmental switches (temp and humidity) regulate strength vs viability
 * indirect relationship between strength and cell viability
 * good to use in applications where crack repair is of importance
 * mortars
 * paving
 * civil and military structures
 * any other light load bearing applications
