<p><br/>Table 8: The effect of natural organic additives on lime-based mortars (4; 9; 5; 35)<br/> <br/>Type of additive Natural compound <br/> <br/> Increasing strength - Sugar, molasses, fats, fruit juices, rye dough, rice starch, gluten, <br/>curdled milk, egg white, vegetable gums, casein, cheese, blood</p>
<p> <br/>Setting time accelerators -Egg white, bullock´s blood, sugar, hog´s lard, casein, starch</p>
<p><br/>Setting time reducers = Sugar, fruit juices, gluten, bullock´s blood, egg white, molasses</p>
<p><br/>Plasticizers - Milk, egg white, fats, sugar, rosin, dung, starch</p>
<p><br/>Aerating agents - Urine, malt, beer</p>
<p><br/>Waterproofing agents and sealants -Fats, oils, waxes, asphalt, sugar materials</p>
<p><br/>Reinforcing fibrous materials -Animal hair, hen, straw, sea-weeds, elm bark, fibrous plants, <br/>cotton, rice paste, barley</p>
