Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_27240 ( "Dry Density (kg/m3)" real, "7-day Compressive Strength (N/mm2)" text, "Thermal Conductivity* (W/mK)" text, "Modulus of Elasticity (kN/mm2)" text, "Drying Shrinkage (%)" text )

### Question ###
If the dry density is 800, what is the drying shrinkage %?

### Accurate SQL ###

SELECT "Drying Shrinkage (%)" FROM table_27240 WHERE "Dry Density (kg/m3)" = '800'
