It is obtained by firing marly limestone, followed by grinding, and is classified as NHL 3.5 according to EN 459-1. Hydraulic lime is a binder that has been used successfully in construction for hundreds of years. It is notable for its setting process and for achieving mechanical strength in contact with water. The carbon dioxide present in the atmosphere also contributes to the hardening process. <\/p>\n<ul>\n<li>Bag: 25kg<\/li>\n<\/ul>\n<p> &nbsp; <strong>For further information about the product, please consult the TECHNICAL DATA SHEET.<\/strong><\/p>\n","protected":false},"featured_media":21697,"comment_status":"open","ping_status":"closed","template":"","meta":{"_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","_seopress_robots_follow":"","_seopress_robots_imageindex":"","_seopress_robots_snippet":"","_seopress_robots_primary_cat":"","_seopress_robots_breadcrumbs":"","_seopress_robots_freeze_modified_date":"","_seopress_robots_custom_modified_date":"","_seopress_robots_canonical":"","_seopress_social_fb_title":"","_seopress_social_fb_desc":"","_seopress_social_fb_img":"","_seopress_social_fb_img_attachment_id":0,"_seopress_social_fb_img_width":0,"_seopress_social_fb_img_height":0,"_seopress_social_twitter_title":"","_seopress_social_twitter_desc":"","_seopress_social_twitter_img":"","_seopress_social_twitter_img_attachment_id":0,"_seopress_social_twitter_img_width":0,"_seopress_social_twitter_img_height":0,"_seopress_redirections_value":"","_seopress_redirections_enabled":"","_seopress_redirections_enabled_regex":"","_seopress_redirections_logged_status":"","_seopress_redirections_param":"","_seopress_redirections_type":0,"_seopress_analysis_target_kw":"","_ayudawp_aiss_exclude":false,"_ayudawp_aiss_exclude_summary":false,"_ayudawp_aiss_summary":"","_ayudawp_aiss_summary_provider":"","_ayudawp_aiss_summary_hash":"","_joinchat":[]},"product_brand":[1180],"product_cat":[810,785],"product_tag":[],"plantillas":[],"test-productos":[],"class_list":{"0":"post-21696","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-seciltek","7":"product_cat-hydraulic-limes","8":"product_cat-limes-and-plasters","10":"first","11":"instock","12":"taxable","13":"shipping-taxable","14":"purchasable","15":"product-type-simple"},"wcpa_form_fields":null,"_links":{"self":[{"href":"https:\/\/redverde.es\/en\/wp-json\/wp\/v2\/product\/21696","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/redverde.es\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/redverde.es\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/redverde.es\/en\/wp-json\/wp\/v2\/comments?post=21696"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/redverde.es\/en\/wp-json\/wp\/v2\/media\/21697"}],"wp:attachment":[{"href":"https:\/\/redverde.es\/en\/wp-json\/wp\/v2\/media?parent=21696"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/redverde.es\/en\/wp-json\/wp\/v2\/product_brand?post=21696"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/redverde.es\/en\/wp-json\/wp\/v2\/product_cat?post=21696"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/redverde.es\/en\/wp-json\/wp\/v2\/product_tag?post=21696"},{"taxonomy":"plantillas","embeddable":true,"href":"https:\/\/redverde.es\/en\/wp-json\/wp\/v2\/plantillas?post=21696"},{"taxonomy":"test-productos","embeddable":true,"href":"https:\/\/redverde.es\/en\/wp-json\/wp\/v2\/test-productos?post=21696"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
